=== On BGA, there is no 1 set strategy (convention) to be played ===
Alice to Bob: "This card is a 5."


* If people start playing different conventions in one game, the game is doomed to fail.
{{cardholder|{{hw|3}}{{hw|4}}{{hw|4}}{{hr|5|n=}} |Bob 🡲}}
* It is a good idea to discuss before the game which conventions you will be using.
|-
!style="background:#ccd4;text-align:center;font-weight:600;"|Play clue
|style="text-align:left;"|Clue that marks a card to play i.e. cannot be a save clue.
|style="text-align:left;"|Alice to Bob: "This card is green."


* The strategies explained in this guide all have 1 goal in mind:
{{cardholder|{{hr|1}}{{hy|2}}{{hg|2|c=}}{{hb|4}} |Bob 🡲}}
** to get the highest possible score, in the most amount of games.
|-
* There are people who find score less important, and want to challenge themselves logically, or "just want to have fun".
!style="background:#ccd4;text-align:center;font-weight:600;"|Focus
** Again, communication in advance of the game is key.
|style="text-align:left;"|The target card of a clue.
|style="text-align:left;"|Alice to Bob: "These 2 cards are 5."


=== The ideal game ===
{{cardholder|{{hr|5|n=}}{{hb|4}}{{hw|4}}{{hy|5|n=|p=🡅}} }}


* Imagine this 'ideal' game.
This clue can be a save so the focus is the chop card.
* You play with 3 players and reach the maximum score of 25 points (5-colour game).
* At the end, there will be (at least) 12 cards left in the hands of the players, (at least) 1 clue token available and 25 cards will have been played.
* This means, that from the 50 cards of the deck, (50 - 25 - 12 =) 13 cards have been discarded and converted into clue tokens.
* You get 8 clue tokens at the start, and you will have gotten a 5 clue tokens from playing the 5s.
* This means that in the entire game, there were 13 (discards) + 8 (start) + 5 (completing a colour) - 1 (token left at the end) = 25 clue tokens available for playing.


* On average, this means 1 clue token per 1 playable card. No matter what variant you play, you will end up with roughly this number.
----
** ''Worst:'' 5-player game, with players that have 4 cards in their hands, playing 5 colours.
*** This gives 22 tokens for 25 cards = 0.88 clue token per card.
** ''Best:'' 2-player game, with players that have 6 cards in their hands, playing 6 colours.
*** This gives 35 tokens for 30 cards = 1.17 token per card.


* The strategies below are based on an optimisation of economical use of the clue-tokens.
Alice to Bob: "These 2 cards are 2."
* The strategies below are only the basic elements of the convention generally played at BGA.
* By combining them and using some logical extrapolations one can derive moves which are even more advanced.
* There are also groups of players on BGA and elsewhere who play with quite different convention sets, where each set has its advantages and downsides.


== Basics ==
{{cardholder|{{hy|2|n=|p=🡅}}{{hg|2|n=}}{{hb|4}}{{hw|4}} }}


* Before all other rules, every player must look at what cards they can see, and deduce what cards in a clue must be or cannot possibly be.
This clue cannot be a save so the focus is the newer (leftmost) card.
** Blindly following the other basic rules without checking for impossible cards will result in mistakes.
|-
** This is critically important with the played and discarded cards, because everybody can see the same things, and so people will give clues knowing that you have this information.
!style="background:#ccd4;text-align:center;font-weight:600;"|Bomb
*** ''For example:'' if the played red stack is up to 3, and there is a red 2 in the discard pile, then you know that you cannot be holding a red 2, so when somebody gives you a clue of 2s, you should read it as "these cards are 2s which are not red" and think about whether that changes the way you interpret the clue.
|style="text-align:left;"|A play that causes a misfire.
*** If you can narrow it down to one or two cards, the clue might mean something other than '''play now'''.
|style="text-align:left;"|{{hTable|1|1|1|1|1}} Alice plays {{hb|3}}
|-
!style="background:#ccd4;text-align:center;font-weight:600;"|Splash
|style="text-align:left;"|Additional new color or rank information of cards that are not the focus.  
|style="text-align:left;"|{{hTable|1|1|1|1|1}}


=== Basic Rule #0 (thinking) ===
{{cardholder|{{hg|2}}{{hb|3}}{{hw|4}}{{hg|4}} |Bob 🡲}}


* '''After you receive a clue, look for every visible card of that type.'''
Alice to Bob: "These 2 cards are green."
* '''Before following other rules, think about whether this changes the meaning.'''
* If there isn't an obvious meaning to the clue, then continue. It is unlikely to be anything complicated.


* The basic game plays with 50 cards: 10 for each colour.
{{cardholder|{{hg|2|c=}}{{hb|3}}{{hw|4}}{{hg|4|c=|p=🡅}} |Bob 🡲}}
* If you want to get the maximum score of 25 points, you need to play 25 cards.
* Some of the cards are left in the players hands at the end of the game.
** Depending on the number of players, this will be 8, 12, 12, or 15 (for 2p, 3p, 4p, and 5p respectively).
** This means in the entire game, there are 17, 13, or 10 cards that can be discarded for clues.
* You also get 8 clue tokens at the start and 4 usable clues from suite completion, making the total number of clues in the entire game 29, 25, or 22.
** This gives the logical conclusion that you can not clue the colour AND number for every card in your hand, because there are simply not enough clues.
* It is therefore paramount, that only useful cards are clued.
* If you mark a card that you know will not be played, it will cost another clue (-1) to make your team mate discard that card to gain a clue (+1), which is a net result of 0.
* If the card is not marked, your team mate will discard it eventually to gain a clue (+1), which is a net result of +1.


=== Basic Rule #1 (cluing) ===
----


Every card that is marked, is either
{{hTable|3|2|2|2|2}}
# (a) useful card(s) to be saved (interpret it as '''hold to play later'''), or
# a useful card to be played (interpret it as '''play now''').
#* Therefore: '''never mark useless cards'''


* Most hanabi-players on BGA play by this main rule.
{{cardholder|{{hr|4}}{{hr|3|n=}}{{hw|3|n=}}{{hb|3|n=}} |Bob 🡲}}
* So when a clue is given, ask yourself "Is this clue to save something"?
** If not, it is to get played.
* Saving cards is important because there are only 2 cards of value 2, 3, and 4 in each suit, and only 1 card of value 5.
* To not get stuck on that colour it is urgent to keep the last copy of a card safe (prevent from discarding it).


* The game interface puts every new card you draw on the left-hand side of your hand.
Alice to Bob: "These 2 cards are red."
* This means, the left-most card is the newest card, which makes your right-most card automatically the oldest.
* If a card has been in your hand for a long time, and you have not been given a clue that marks it, it is logical that it is a useless card and safe to discard.


=== Basic Rule #2 (discarding) ===
{{cardholder|{{hr|4|c=}}{{hr|3|n=|c=}}{{hw|3|n=}}{{hb|3|n=}} |Bob 🡲}}


* '''Discard first what you know is useless (like a clued 1 when all 1s are already played).'''
Play clue for {{hr|4}} which splashes {{hr|3}}.
* '''After that: discard your oldest (right-most) un-clued card.'''
|-
!style="background:#ccd4;text-align:center;font-weight:600;"|Reclue
|style="text-align:left;"|A repeated clue that causes marked card(s) to play.
|style="text-align:left;"|{{hTable|2|1}} {{cardholder|{{hr|2}}{{hg|4}}{{hw|4}}{{hy|2|c=}} |Bob 🡲}}


* ''Note:'' this rule is already a bit tricky.
Bob does not yet know his marked yellow is playable.
** At the start of the game, every card can be considered equally old.
** This is where personal preference of players starts to matter.


* Another result from the newest --> oldest order, is the interpretation of multiple marked cards.
Alice to Bob: "This card is yellow."
* When you haven’t been clued a certain kind of clue (call it "X"), while there were tokens, and right after you draw a card, you receive a "X" clue on multiple cards including the newest and you can identify it as a play clue (see Basic Rule 1), you can logically deduce that the newest (left-most) card is the one to play.
|-
* If an older card was "the playable card", it would probably have been clued earlier – provided you can identify your teammates did have the opportunity to give the same clue earlier.
!style="background:#ccd4;text-align:center;font-weight:600;"|Fix clue
* The logical conclusion must be that the card in the leftmost slot was the card your team have been waiting for (the "wait factor"), and you happened to draw it.
|style="text-align:left;"|Follow-up clue required to change the focus of a play clue (and prevent a misfire).
|style="text-align:left;"|{{hTable|1}}


=== Basic Rule #3 (playing) ===
Alice to Cathy: "These 2 cards are white."


* '''If the wait factor is validated, play the newer (left-most) clued card'''
{{cardholder|{{hw|2|c=}}{{hw|1|c=}}{{hr|1}}{{hb|3}} |Cathy 🡲}}
* So most people on BGA expect you to '''only''' play the clued card on the left.
The rest of the cards are just to be kept on your hand.
Beware that there are different approaches and not all players play by this convention.


=== Basic Rule #4 (triggering end of game) ===
Bob to Cathy:  "This card is a 2."


* Once all cards have been drawn, each player has one more play, including the player who drew the last card.
{{cardholder|{{hw|2|c=|n=}}{{hw|1|c=}}{{hr|1}}{{hb|3}} |Cathy 🡲}}
* Therefore, it is often useful to delay the end of game by giving worthless or low-value clues instead of discarding.
|-
!style="background:#ccd4;text-align:center;font-weight:600;"|Prompt
|style="text-align:left;"|A play clue that causes connecting marked card(s) to play.  
|style="text-align:left;"|{{hTable|2|5|1|3|4}}


=== Basic Example ===
{{cardholder|{{hb|5}}{{hy|4}}{{hr|3|c=}}{{hw|5}} |Bob 🡲}}
{{cardholder|{{hw|2}}{{hw|4}}{{hy|1}}{{hr|4}} |Cathy 🡲}}


Imagine the following starting situation:
Alice to Cathy: "This card is red."


          (newest ... oldest)
{{cardholder|{{hb|5}}{{hy|4}}{{hr|3|c=}}{{hw|5}} |Bob 🡲}}
  Alice:  W1, Y1, B2, Y2, B2
{{cardholder|{{hw|2}}{{hw|4}}{{hy|1}}{{hr|4|c=}} |Cathy 🡲}}
  Barry:  G1, G1, W3, Y2, B1
  Carla:  B1, R4, W4, R3, G3


* Alice can clue 1s to Barry. But that will mark both G1's, so it's not the best option.
Bob plays {{hr|3|c=}}.
* Better is for Alice to clue Carla 1s, or blue.
Cathy plays {{hr|4|c=}}.
** ''If '''blue'''-clue is given, then Carla will not worry about the B1 in Barry's hand that is about to be discarded.''
|}
:: ''Both 1-clue or '''blue'''-clue only mark 1 card, so give equal information about the other cards in Carla's hand.''
¹Some uncommon convention sets allow color saves.


* Barry will clue 1s to Alice.
{{infoBox
* He knows that Carla prefers to play her 1.
|maxWidth=
* And Barry is the only person who can see that the 1s in both Alice's hand, and Carla's hand are different.
|state=collapsed
|title=Save clue thought process
|body=
{{hTable|1|1|1|1|}} {{hDiscard|w=2}}


* Everyone will have to wait for B2 to be discarded, before the second B2 can be clued.
{{cardholder|{{hr|2}}{{hy|4}}{{hr|3}}{{hw|5}} |Bob 🡲}}
* Everyone will also have to wait for G1 to be discarded, before the second G1 can be clued.
{{cardholder|{{hr|4}}{{hy|3}}{{hr|4}}{{hw|2}} |Cathy 🡲}}
** Alternatively, when R1 is drawn and clued, then both G1's may be clued, since all 1's will be played and all cards marked 1 can be safely discarded.


So, the first four moves are:
Alice to Bob: "This card is a 5."


1. Alice clues '''blue''' to Carla (7 clue-tokens).
{{cardholder|{{hr|2}}{{hy|4}}{{hr|3}}{{hw|5|n=}} |Bob 🡲}}
{{cardholder|{{hr|4}}{{hy|3}}{{hr|4}}{{hw|2}} |Cathy 🡲}}


2. Barry clues 1 to Alice (6 clue-tokens).
Bob knows that there is only one 5 of each color in the deck, so all 5s need to be marked to keep them from being discarded. Bob sees Cathy's oldest card is {{hw|2}} and checks the discard pile to see if he needs to save it from being discarded. There is already a {{hw|2}} in the discard pile and Bob knows there are only two 2s of each color, so Cathy has the last remaining {{hw|2}} and Bob must save it.  


3. Carla plays B1 and draws R1.
Bob to Cathy: "This card is a 2."


4. Alice plays W1 and draws G4.
Good job, Bob.


The game now looks like this, with Barry to move:
{{cardholder|{{hr|2}}{{hy|4}}{{hr|3}}{{hw|5|n=}} |Bob 🡲}}
{{cardholder|{{hr|4}}{{hy|3}}{{hr|4}}{{hw|2|n=}} |Cathy 🡲}}


          (newest ... oldest)
Cathy looks at the played cards to see if 2s are all playable. The {{hw|1}} has not been played yet, so she cannot be sure it is playable yet. Next, Cathy looks at the discard pile to see if there is a 2 in the discard pile. There is a {{hw|2}} discarded, so she interprets this number clue marking her oldest card as a save clue to prevent her from discarding it. Nice one, Cathy.}}
  Alice:  G4, Y(1), B2, Y2, B2                  Played: R0, Y0, G0, B1, W1
  Barry:  G1, G1, W3, Y2, B1
  Carla:  R1, R4, W4, R3, G3                    Discarded: -


5. Barry clues '''red''' to Carla.

* Sometimes you have a card to play but the next player’s chop card is critical and you have no tokens to tell them.

** '''''Always try to give them a clue token to use or help them play their hand as fast as possible.'''''
Cathy plays {{hb|1}}.

* You want to give a clue, but you have no remaining clue-tokens.

* In this case, you can discard the card in the same position as the card that you want that player to play.


==== Example Positional Discard ====
Bob plays {{hy|1}}.


* All players have agreed on the convention that a colour-clue means '''play''' the left-most marked card.

{{cardholder|{{hy|4}}{{hb|1|c=}}{{hr|4}}{{hw|2}} |Cathy 🡲}}


* If Player 1 is given a 4-clue, the G4 will be saved, but the Y3 will be the new '''chop''' card.
Bob discards {{hw|1}} (because he has nothing to clue or play).
* One option to save both Y3, and G4 is to give Player 1, a 1-clue.
|-
* This would make the R1 the new '''chop''' card, and the G1 will be the next '''chop''' card.

{{cardholder|{{hy|3}}{{hw|2}}{{hg|4}}{{hb|5}} |Cathy 🡲}}


* This is an alternative solution if you are low on clue-tokens, or don't have enough players to execute multiple saves in a row.
Alice discards her chop instead of playing {{hBack|3|n=}}.

|style="text-align:left;"|An unexpected discard to save a critical card in another hand.

{{cardholder|{{hBack}}{{hBack}}{{hBack}}{{hBack}} |Alice 🡲}}
{{cardholder|{{hy|4}}{{hb|3}}{{hr|4}}{{hw|5}} |Bob 🡲}}


  Player 1: G1, R1, B4, Y3, G4
Alice discards slot '''3'''.


* This situation is similar as the Hint to Discard.
Bob expected Alice to discard her chop.
* However, in this situation a 1-clue will be interpreted as '''play''' G1 (which isn't playable).
* To save both Y3 and G4, an empty clue can be given to Player 1 (either 2 or 5 or white in this situation).
* This will cause them to wonder why you would be wasting a clue to give no information, and find out it must be because cluing normally would enable you to save one '''chop''' card, not two.
* So it costs 1 clue-token for 2 saves, but gives you no information about the saved cards.


== 3+ Players ==
Bob's chop must be critical.

* Therefore the game play is different from 3+P games.
{{cardholder|{{hr|1}}{{hb|2}}{{hr|4}}{{hr|5}} |Bob 🡲}}


=== Prompt ===
Alice plays her chop card.


* A prompt can clarify (an) already marked card(s) to be played as well as mark the next card to play.
Bob expected Alice to discard her chop.


==== Example Prompt ====
Alice is unable to perform a scream discard.


          (newest ... oldest)
Bob's chop must be critical.
  Alice: XX, XX, XX, XX, XX                  Played: R0, Y1, G0, B2, W0
|-
  Barry: ??, ??, ??, ?2, ?5
!style="background:#ccd4;text-align:center;font-weight:600;"|Duplicate discard
  Carla: Y3, G5, R4, B3, W1                  Discarded: -
|style="text-align:left;"|Discard of a duplicate marked copy of a card in another hand.
* Alice gives a yellow-clue to Carla, marking Y3 as '''play'''.
|style="text-align:left;"|{{hTable||1}}
* Barry sees that the Y3 is '''almost''' playable.
* This means that Barry has the '''logical''' in-between step:
** Barry has to play Y2.
** In this case, the Y2 is not on the '''draw''' card.
** The logical place for that card is the already marked 2.
* So Barry can assume that his card between his '''chop''' and the 5 is the Y2.


=== Finesse ===
Alice to Bob: "This card is green."


* This advanced move can get you 2 cards into play, with only 1 clue-token.
{{cardholder|{{hw|4}}{{hg|2|c=}}{{hy|4}}{{hr|3}} |Alice 🡲}}
* You do this, by marking an '''almost''' playable card as playable.
{{cardholder|{{hy|3}}{{hr|4}}{{hg|5}}{{hg|2|n=|c=}} |Bob 🡲}}
* Someone else will have to play the '''logical''' in-between step, to make the card genuinely playable.

* Barry sees that the B2 is '''almost''' playable.
* This means that Barry has the '''logical''' in between step:
** Barry has to play B1.
** The only logical place for that card is at the '''left-most position''' so Barry can assume that the '''draw''' card is the playable B1.
** If it was somewhere else in your hand, the card would have been clued earlier.
* '''''Note:'' for the in-between player, a prompt always has priority over a finesse; if a player has a marked card that can be the in-between card, they should play it.'''


==== Example Finesse (#2) ====
Alice to Cathy: "This card is red."


          (newest ... oldest)
{{cardholder|{{hr|2}}{{hy|1}}{{hw|1}}{{hb|3}} |Alice 🡲}}
  Alice:  ??, ??, ??, ??, ??                  Played: R0, Y1, G2, B0, W1

  Carla:  XX, XX, R2, XX, XX                  Discarded: G4, R3
* Alice gives a 5-clue to Barry, saving W5 and G5 from being discarded.
* Barry sees nothing of interest in the hand of Carla, so discards his '''chop''' (R1) and draws R4.
* Carla gives a setup for Alice by marking Y2 with a yellow-clue.
* The game now looks like this:
          (newest ... oldest)
  Alice:  ??, ??, ??, ??, ??                  Played: R0, Y1, G2, B0, W1
  Barry:  R4,*Y2, R1, G5*,W5*
  Carla:  XX, XX, R2, XX, XX                  Discarded: G4, R3, R1
* Alice can't give a red-clue to Barry, because this would cause Barry to bomb with r4.
* Instead, Alice now gives a red-clue to Carla, marking R2 as '''play'''.
* Barry sees that the R2 is '''almost''' playable.
* This means that Barry has the '''logical''' in between step:
** Barry has to play R1.
** Barry knows that R1 can only be at the '''draw''' position, or at the middle position.
* Since Alice deliberately let Barry discard a playable R1 the round before, Barry concludes that he was already holding a second R1 at the time.
* Therefore, the '''logical''' place for the R1 to be, is at the middle position; '''not''' the '''draw''' position.


=== Bluff ===
If Alice discarded instead, Bob would have clued Alice red to finesse {{hr|1}} and {{hr|2}}.


* This works the same as finesse. Only this time, the '''logical''' in between step, is a different playable card, so the player is tricked.
|title2=Good Skip (ensures good touch)
* It is slightly less strong than finesse, because it gives 1 play + 1 save for 1 clue-token.
|body2={{hTable|1|1|1|1|1}}


==== Example Bluff ====

{{cardholder|{{hw|2}}{{hr|1}}{{hb|2}}{{hg|1}} |Cathy 🡲}}


          (newest ... oldest)
Alice skips Bob to give Cathy a blue clue so that a duplicate {{hw|2}} is not marked.
  Alice:  XX, XX, XX, XX, XX                  Played: R0, Y3, G1, B1, W0
}}
  Barry:  W1, B3, R4, B2, G5
  Carla:  ??, ??, R?, ??, ??                  Discarded: -
* Alice gives a red-clue to Carla, marking it as '''play'''.
* Barry sees that the R2 is '''almost''' playable, so applies finesse logic and plays his '''draw''' card.
* Much to Barry's surprise, he has not played R1, but W1 (which was also playable).
* Because Carla saw Barry playing his '''draw''', which was a different colour than the clue he received, Carla knows it was a bluffed finesse situation.
* She concludes that her red card is R2, and saves it for later.

* This works the same as finesse. Only this time, the '''logical''' in between step, is a different players hand.
Alice to Cathy: "This card is white."
* This also gets 2 plays for 1 clue-token, but takes longer than a normal finesse.


==== Example Reverse ====

Cathy also sees {{hw|2}} and could hold {{hw|3|c=}}.<br>
  Barry:  ??, ??, W?, G3, ??
Cathy discards.
  Carla:  W1, B2, R4, B3, G5                  Discarded: -
* Alice gives a white-clue to Barry, marking it as '''play'''.
* However, Barry sees that the '''draw''' card of Carla is a playable card of the same colour.
** Therefore, Barry may assume that it is (reversed) finesse, and that his white '''might''' be W2, nearly playable.
* Barry decides to then first play his G3, which is a safer option for the moment, and see how Carla reacts.
* Carla recognises the (reversed) finesse play, and plays her '''draw''' card to play the W1.


=== Having the optimal player draw the last card (endgame) ===
{{cardholder|{{hr|5}}{{hw|2}}{{hy|4}}{{hg|1}} |Bob 🡲}}
{{cardholder|{{hy|5}}{{hw|3|c=}}{{hb|3}}{{hg|3}} |Cathy 🡲}}


* At the end of the game, the person who draws the last card (which happens either by playing or discarding) triggers the end of the game.
Bob plays {{hw|2}}.
* After the last card is drawn, each player receives exactly one more turn.
Cathy plays {{hw|3|c=}}
* Sometimes near the end of the game you will want a specific player to play or discard in order to get the last turn.

* Easy to execute.

Con's:
* Double discard possible for 4s.
* Easy to get the hands locked.


==== Guidelines ====
Bob sees {{hb|1}} in Cathy's hand, but layered<br> behind other playable cards {{hr|2}} and {{hy|2}}.<br>
Bob discards. Cathy plays {{hr|2}}.


# Number-clue means “save all the cards that were marked by this clue”.
{{cardholder|{{hg|3}}{{hb|2|c=}}{{hb|5|c=}}{{hy|1}} |Bob 🡲}}
#* Try to give save-clues as late as possible.
{{cardholder|{{hw|5}}{{hy|2}}{{hb|1}}{{hg|1}} |Cathy 🡲}}
# Non-unique 2s and 3s must be saved as much as possible.
#* ''Try to avoid double saves if possible.''
#* Unique cards should always be saved.
# Colour-clues mean “play the newest card that was marked by this clue”.
#* Other cards that are marked by the clue may be discarded when not previously marked by a number-clue.
# If more than 5 clue-tokens are available, discarding unknown cards should be avoided, but known useless cards may be discarded freely.
# If there is only 1 clue-token available, colour-clues may be given only
## If it leads to two or more plays in a row.
## If the playable card is on '''chop'''.
# A colour-clue may re-mark a card that’s already marked by a number if:
## It also marks a previously unmarked card that is playable. (Either immediately, or immediately after playing the card that was marked with a number.)
## As a stall-clue (see next).
# When just 2 of the hand-slots are filled with non-saved cards, that player should try to avoid discarding two turns in a row (including the turn after the save-clue that leads to this state).
# If a clue is given while avoiding discarding twice in a row:
#* guideline 4 no longer applies; also stall clues may be given:
## A colour-clue that re-marks a saved card, without marking an unmarked card.
##* ''For example:'' to indicate an accidental double save, or to clarify a playable card.
## An empty-clue: a clue that marks none of the cards. This can be used to convey information on multiple playable cards.
## A 5-clue. If 5a and 5b are not possible, a re-clue on the 5s is allowed.
# Nearing the end of the game, when the number of saved cards in all the hands + the number of cards in the deck is equal to the number of card that need to be played to get the maximum (possible) score, discarding should be avoided as much as possible - so stall clues may be given, non-unique 4s may be saved, etc.


=== Strategy #2 ===
Cathy knows this cannot be a bluff because<br> Bob would not discard unless he sees a playable {{hb|1}} in Cathy's hand.<br>
So Cathy is promised {{hb|1}} and keeps playing<br> each slot from left to right until a {{hb|1}} is played.

# The Mid game: Everything that's not early or late game.

|style="text-align:left;"|{{hTable|2|4|4|4|4}} {{Hclue|0}}


* In the early game, the goal is to 'sort' the hand cards into "old" cards and "new" cards.
{{cardholder|{{hBack}}{{hBack}}{{hBack}}{{hBack}} |Alice 🡲}}
* Since all cards are equally old in the beginning, it is unclear which cards are relevant, and which aren't.
{{cardholder|{{hb|2}}{{hr|3}}{{hr|4|n=|c=}}{{hr|5|n=|c=}} |Bob 🡲}}
* In order to do so, players follow these guidelines:
*# Players are not allowed to discard before 3 clue-tokens are spent.
*# After the early game, the right-most un-clued cards will be considered "old" and therefore discard-able. So the focus of the clues in the early game should be to save the valuable three right-most cards.
*# 1s should be marked with colour as much as possible.
*# A 1-clue should only be given when it marks three or more unique 1s.
*# 4-clues should only be given, when the 4 is blocking a colour-clue in the future. Cards marked with 4 in the early game should be discarded in the mid game.


===== Mid game =====
Alice blind plays '''slot 2''' and causes a misfire.


* In the mid game, the goal is to play as many playable cards as possible, and save as many useful cards as possible.
Bob expected Alice to discard her chop.
* In order to do so, players follow these guidelines:
*# Players will be as efficient as possible with clue-tokens.
*#* Re-marking cards (spending a clue-token that gives '''more''' information on a saved card) is highly discouraged.
*# All 2s, 3s and 5s must be saved, even when the 2s or 3s are not unique.
*## Any clue means "play the newest, '''previously unmarked''', card".
*##* With the exception of a '''save'''-clue, or a correction-clue.
*## A card can be saved in four possible ways:
*### A number-clue that marks the '''chop''' card.
*### A colour-clue that marks a '''play''' card, and in addition marks another card of the same colour.
*###* This other card is saved.
*### A '''scream''' discard. When player 1 can play a card, but chooses to discard instead, it is called a '''scream''' discard.
*###* This signals to player 2 that their '''chop''' card must be saved.
*###* It is recommended that player 2 spends the token, in case they have a long chain of cards that need saving.
*### A deliberate misplay. When player 1 gives player 2 a '''play'''-clue, that causes player 2 to '''bomb'''.
*###* Player 2 knows to '''save''' all the cards '''older''' than the card that was used to bomb.
*## When a useless card is marked as '''save''', it is desired to give a correction-clue.
*##* This re-marks the card, indicating its uselessness.
*##* Preferably, this shouldn't mark any other cards.
*##** When it does, the clue is a '''play'''-clue with the correction as an additional benefit.
*# Double discarding (discarding a card that could be the same card that was just discarded), is not allowed.
*# Play-clues shouldn't be given when there are 3 or less clue-tokens available, except when it leads to more than 1 '''play'''.
*# When a player has only two unmarked cards in their hand (all other slots are filled with '''saves'''), then this player should keep discarding to a minimum.
*# When a player has only one unmarked card in their hand, then this player is forbidden to discard two turns in a row.

== Gameplay Using Finesse Conventions ==
 
==== Receiving Clues ====
 
Check visible cards, including played and discarded, to determine the focus and the meaning of a clue.
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Example A: you are given a '''2''' clue. You see {{hr|2}} was played and the second {{hr|2}} is in another hand. Therefore the clue means "2s which are not red".</li>
  <li>Example B: you are given a 4 clue that marks only your chop. You see no 4s have been discarded and no 4s on the chop of the players next to you. Therefore the clue means "this 4 is playable".</li>
</ul>
 
==== Giving Clues ====
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>'''Don't mark trash cards''' (see Good Touch Principle).</li>
  <li>Save critical cards as priority.</li>
    <ul>
      <li>Look ahead for critical cards on chop. ''Sometimes more than one player must help to save consecutive critical cards.''</li>
    </ul>
  </li>
  <li>With few {{Hclue|s=1}}, work out which players need them.</li>
  <li>Consider how the receiver can interpret your clue.</li>
</ul>
 
==== Discarding ====
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Trust your teammates to manage your cards.
  <li>When there is nothing urgent to clue, don't be afraid to discard! Discarding is often the best move for the team.
</ul>
 
==== Playing ====
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>When multiple cards are marked, determine the focused card. ''Each clue only has one focused card.''
  <li>Logically playable cards are marked at the earliest opportunity, so the leftmost card is assumed to be the focus of play clues ''(where no other cards are known to be playable)''.
</ul>
 
==== Triggering the final round ====
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Sometimes a specific player should draw the last card to maximize the score.
  <li>Giving empty clues (e.g., "You have no red card") can help to manage which player draws the last card.
</ul>
 
{{infoBox |maxWidth=650 |state=collapsed
|title=Last Card Example
|body={{hTable|5|5|3|4|5|d=1}} {{hclue|4}}

{{cardholder|{{hg|2}}{{hr|1}}{{hg|4|n=|c=}}{{hg|5|n=|c=}} |Cathy 🡲}}
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Alice and Bob both give empty clues. e.g., Alice to Cathy: "You have no white card."
  <li>Cathy plays {{hg|4}} and draws the last card.
  <li>Alice discards, Bob plays {{hb|5}} and Cathy plays {{hg|5}}.
</ul>
}}

</ul>
 
== 2 Player Strategy ==
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Saves are given as late as possible.
  <li>Off-chop saves for consecutive critical cards.
  <li>Double discards can be avoided with a stall clue.
  <li>Last {{Hclue|s=1}} is reserved to mark a critical or playable chop.
  <li>Playable first copies are clued.
  <li>Splash critical and already-marked trash cards.
  <li>Play in clued order.
  <li>Before playing, consider marking a connecting chop card.
  <li>Scream discard = save the chop card (and move chop one slot to the left).
  <li>Flamboyants: Consider not locking a hand with a 5 save.
  <li>Avalanche: Any card can be multicolor. e.g. wait for negative multicolor on a {{hr|5|c=|n=}} before playing as {{hr|5|c=|n=}}.
  <li>Avalanche: Playable cards marked with both color and number play first.
  <li>Black Powder: {{hk|1}} is only marked on chop unless all other 1s (or {{hk|2}}) are already clued/played.
</ul>
 
==== Early game ====
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Avoid discarding until at least {{Hclue|s=1.2|3}} are used.
  <li>With multiple marked unknown 1s in your hand, consider first playing your 1s or marking 1s individually with color.
  <li>Non-critical 2s / {{hk|4}} can be marked with number.
</ul>
 
==== Alternative Strategy ====
 
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>'''Any card may be saved''', including non-critical cards.
  <li>Cards marked with a number are only splashed with color:
    <ul>
      <li>If a previously unmarked card is playable.
      <li>As a stall clue.
    </ul>
  </li>
</ul>
 
== Other Convention Sets ==
 
==== Finesse Additional Skip Interpretation ====
 
{{warn|This convention prevents discard management, finesse with number, layered finesse}}
An additional convention is that skipped player(s) cannot discard. i.e., Alice can clue Cathy only if Bob has a play or can give another useful clue. If a skipped player has no marked playable cards and no good clue to give, they must blind play their newest, unmarked card. A clue-giver who causes unmarked play(s) purely from a skip is responsible for any misinterpretation.
 
{{infoBoxes
|maxWidth=650
|state=collapsed
|title1=Skipped Players Cannot Discard Example
|body1=Alice skips Bob to give Cathy a '''1''' clue.
 
{{hTable}}
 
{{cardholder|{{hy|1}}{{hy|2}}{{hw|2}}{{hr|2}} |Bob 🡲}}
{{cardholder|{{hw|2}}{{hr|1|n=}}{{hb|2}}{{hg|4}} |Cathy 🡲}}
 
Bob has no clue to give and no known play, so he blind plays his newest unmarked card. {{hy|1}} does not connect to {{hBack|1|n=}}, so Cathy interprets Bob's move as a skip play and plays {{hr|1|n=}}.
 
|title2=Forbidden Skip Example
|body2=Alice skips Bob to give Cathy a '''3''' clue.
 
{{hTable|2}}
 
{{cardholder|{{hy|1}}{{hy|2}}{{hw|2}}{{hr|2}} |Bob 🡲}}
{{cardholder|{{hw|2}}{{hr|3|n=}}{{hb|2}}{{hr|1}} |Cathy 🡲}}
 
Bob has no clue to give and no known play, so he blind plays his newest unmarked card. In this convention, {{hy|1}} does not connect to {{hBack|3|n=}}, so Cathy interprets as a bluff and her {{hBack|3|n=}} is not playable.
This is a lie because {{hr|3|n=}} is playable. So Alice is forbidden from giving this clue. Instead, Alice should have discarded and allowed Bob to clue Cathy so that she knows her {{hr|3|n=}} is playable.

==== H-Group ====
 
Some key differences include:
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>non-critical saves
  <li>chop-focused play clues
  <li>context-dependent chop moves
  <li>number play clues are assumed to be a lie (bluff) over truth (finesse).

red2,with a red 2clue,yellow4,with a yellow 4clue,red3,with a red 3clue,white5,with a white 5clue, Bob 🡲 red4,with a red 4clue,yellow3,with a yellow 3clue,red4,with a red 4clue,white2,with a white 2clue, Cathy 🡲

Alice to Bob: "This card is a 5."

Bob knows that there is only one 5 of each color in the deck, so all 5s need to be marked to keep them from being discarded. Bob sees Cathy's oldest card is white2,with a white 2clue, and checks the discard pile to see if he needs to save it from being discarded. There is already a white2,with a white 2clue, in the discard pile and Bob knows there are only two 2s of each color, so Cathy has the last remaining white2,with a white 2clue, and Bob must save it.

Bob to Cathy: "This card is a 2."

Good job, Bob.

red2,with a red 2clue,yellow4,with a yellow 4clue,red3,with a red 3clue,white5,with a white 5clue, Bob 🡲 red4,with a red 4clue,yellow3,with a yellow 3clue,red4,with a red 4clue,white2,with a white 2clue, Cathy 🡲

Cathy looks at the played cards to see if 2s are all playable. The white1,with a white 1clue, has not been played yet, so she cannot be sure it is playable yet. Next, Cathy looks at the discard pile to see if there is a 2 in the discard pile. There is a white2,with a white 2clue, discarded, so she interprets this number clue marking her oldest card as a save clue to prevent her from discarding it. Nice one, Cathy.

Early save An attempt to save a card when there is already a known playable card in the same hand.
​This clue should be read as a play clue.
This clue is a mistake, since save clues should only be given after all playable cards are played when the chop card is in danger of discard.

blue3,with a blue 3clue,red4,with a red 4clue,white5,with a white 5clue,red2,with a red 2clue, Cathy 🡲

Double discard Two consecutive players discard copies of the same chop card, resulting in a critical discard.
​A special problem, since, to each of the consecutive players, a number clue that marks their chop card does not look like a save clue (and therefore looks like a play clue).

Bluff seat The player directly before the player who is bluffed.
​The bluff seat is an H-Group convention which restricts which players are allowed to perform a bluff. Outside of H-Group, it is possible to bluff any player when the players before were unable to blind play (to reveal the bluff).
Order is Alice 🡆 Bob 🡆 Cathy:

Alice is in the 'bluff seat' of Bob.
Bob is in the 'bluff seat' of Cathy.
Cathy is in the 'bluff seat' of Alice.

Discard clue Clue that marks trash card(s) to be discarded (to prevent a misfire or unwanted discard).
​The receiver must know that all cards marked by this clue are trash.

Alice to Bob: "You have no 2."

Skip/Steal A player gives a clue that could have been given by one of the skipped players.
​The players who were skipped have a better move than to give the clue that skipped them.

Good reasons for skipping players:

  • Clue-giver is locked, i.e., cannot play or discard.
  • Gain tempo to play, e.g., skipped player(s) all have playable cards.
  • Gain tempo to clue, e.g., skipped player(s) must give a fix clue.
  • Avoid a bad/ensure a good clue, e.g., mark cards with good touch.
  • Cause a discard, e.g., duplicate or trash card.
  • Avoid a discard, e.g., double discard or nice-to-have card that cannot be saved.

Gameplay Using Finesse Conventions

Receiving Clues

Check visible cards, including played and discarded, to determine the focus and the meaning of a clue.

  • Example A: you are given a 2 clue. You see red2,with a red 2clue, was played and the second red2,with a red 2clue, is in another hand. Therefore the clue means "2s which are not red".
  • Example B: you are given a 4 clue that marks only your chop. You see no 4s have been discarded and no 4s on the chop of the players next to you. Therefore the clue means "this 4 is playable".

Giving Clues

  • Don't mark trash cards (see Good Touch Principle).
  • Save critical cards as priority.
    • Look ahead for critical cards on chop. Sometimes more than one player must help to save consecutive critical cards.
  • With few ​ clue tokens, work out which players need them.
  • Consider how the receiver can interpret your clue.

Discarding

  • Trust your teammates to manage your cards.
  • When there is nothing urgent to clue, don't be afraid to discard! Discarding is often the best move for the team.

Playing

  • When multiple cards are marked, determine the focused card. Each clue only has one focused card.
  • Logically playable cards are marked at the earliest opportunity, so the leftmost card is assumed to be the focus of play clues (where no other cards are known to be playable).

Triggering the final round

  • Sometimes a specific player should draw the last card to maximize the score.
  • Giving empty clues (e.g., "You have no red card") can help to manage which player draws the last card.
Last Card Example
1cards in the deckred5yellow5green3blue4white5multicolorblack powder 4 clue tokens

red3,with a red 3clue,yellow1,with a yellow 1clue,green1,with a green 1clue,blue5,with a blue 5clue, Bob 🡲 green2,with a green 2clue,red1,with a red 1clue,green4,with a green 4clue,green5,with a green 5clue, Cathy 🡲

  • Alice and Bob both give empty clues. e.g., Alice to Cathy: "You have no white card."
  • Cathy plays green4,with a green 4clue, and draws the last card.
  • Alice discards, Bob plays blue5,with a blue 5clue, and Cathy plays green5,with a green 5clue,.

2 Player Strategy

  • Saves are given as late as possible.
  • Off-chop saves for consecutive critical cards.
  • Double discards can be avoided with a stall clue.
  • Last ​ clue tokens is reserved to mark a critical or playable chop.
  • Playable first copies are clued.
  • Splash critical and already-marked trash cards.
  • Play in clued order.
  • Before playing, consider marking a connecting chop card.
  • Scream discard = save the chop card (and move chop one slot to the left).
  • Flamboyants: Consider not locking a hand with a 5 save.
  • Avalanche: Any card can be multicolor. e.g. wait for negative multicolor on a red5,with a red 5clue, before playing as red5,with a red 5clue,.
  • Avalanche: Playable cards marked with both color and number play first.
  • Black Powder: black powder1,with a black powder 1clue, is only marked on chop unless all other 1s (or black powder2,with a black powder 2clue,) are already clued/played.

Early game

  • Avoid discarding until at least 3 clue tokens are used.
  • With multiple marked unknown 1s in your hand, consider first playing your 1s or marking 1s individually with color.
  • Non-critical 2s / black powder4,with a black powder 4clue, can be marked with number.

Alternative Strategy

  • Any card may be saved, including non-critical cards.
  • Cards marked with a number are only splashed with color:
    • If a previously unmarked card is playable.
    • As a stall clue.

Other Convention Sets

Finesse Additional Skip Interpretation

​This convention prevents discard management, finesse with number, layered finesse

An additional convention is that skipped player(s) cannot discard. i.e., Alice can clue Cathy only if Bob has a play or can give another useful clue. If a skipped player has no marked playable cards and no good clue to give, they must blind play their newest, unmarked card. A clue-giver who causes unmarked play(s) purely from a skip is responsible for any misinterpretation.

Skipped Players Cannot Discard Example
Alice skips Bob to give Cathy a 1 clue.

cards in the deckredyellowgreenbluewhitemulticolorblack powder

yellow1,with a yellow 1clue,yellow2,with a yellow 2clue,white2,with a white 2clue,red2,with a red 2clue, Bob 🡲 white2,with a white 2clue,red1,with a red 1clue,blue2,with a blue 2clue,green4,with a green 4clue, Cathy 🡲

Bob has no clue to give and no known play, so he blind plays his newest unmarked card. yellow1,with a yellow 1clue, does not connect to card back1,with a 1clue,, so Cathy interprets Bob's move as a skip play and plays red1,with a red 1clue,.
Forbidden Skip Example
Alice skips Bob to give Cathy a 3 clue.

cards in the deckred2yellowgreenbluewhitemulticolorblack powder

yellow1,with a yellow 1clue,yellow2,with a yellow 2clue,white2,with a white 2clue,red2,with a red 2clue, Bob 🡲 white2,with a white 2clue,red3,with a red 3clue,blue2,with a blue 2clue,red1,with a red 1clue, Cathy 🡲

Bob has no clue to give and no known play, so he blind plays his newest unmarked card. In this convention, yellow1,with a yellow 1clue, does not connect to card back3,with a 3clue,, so Cathy interprets as a bluff and her card back3,with a 3clue, is not playable.

This is a lie because red3,with a red 3clue, is playable. So Alice is forbidden from giving this clue. Instead, Alice should have discarded and allowed Bob to clue Cathy so that she knows her red3,with a red 3clue, is playable.

H-Group

Some key differences include:

  • non-critical saves
  • chop-focused play clues
  • context-dependent chop moves
  • number play clues are assumed to be a lie (bluff) over truth (finesse).
