General rules for Hanabi:
== Introduction ==
The '''CHOP''' card is the un-clued card which is furthest to the '''RIGHT'''.
Hanabi is a cooperative game. Your goal, as a team, is to build a fabulous fireworks show. You do this by playing the cards in the correct order. However, you cannot see your own cards; you can only see the cards of your team mates.
The '''DRAW''' card is the un-clued card which is furthest to the '''LEFT''', almost always this is the left card.


1) New cards come from the left so '''DISCARD''' cards from '''RIGHT'''
'''Final Score Ratings'''


2) Save - Sometimes players can have important cards that not playable immediately. '''TO SAVE''' a card, '''WAIT UNTIL''' the card is the '''CHOP''' card and clue it '''BY NUMBER'''.

3) To make somebody to put(place/play) card there are 2 ways:
== Card distribution ==
  3.1 '''BY COLOUR''': when you get or give color clue it means '''LEFT COLORED CARD PLAYABLE''' (unless the clue provides more information on another card)
In a game of Hanabi on NORMAL DIFFICULTY, the deck contains 50 cards. Each has exactly one colour: either Red, Yellow, Green, Blue, or White.
  3.2 '''BY NUMBER''': when you get or give a number clue it means '''LEFT COLORED CARD PLAYABLE''' (unless it provides more information on another card AND it is not a '''SAVE''' clue)
  3.3 could be another variants(if you got 222 remember that all of them could be played after all 111111)


4) Try not clue cards which can never be played because they won't discard those cards until you use another clue on them or they can use the process of elimination to determine that they aren't playable.
There are 10 cards in each colour:
* three 1s
* two 2s
* two 3s
* two 4s
* one 5


5) Try not to give unnecessary clues. In advanced play, every clue is played with a purpose behind it.
===Multicolour cards===
There are three variants that add a 6th colour: the multicolour.


Advanced Tactics:
# TRICKY DIFFICULTY adds 10 multicolour cards to the normal game. These cards get marked by a separate multicolour clue.
# HARD DIFFICULTY adds '''5''' multicolour cards to the normal game: one of each number. These cards get marked by a separate multicolour clue.
# VERY DIFFICULT DIFFICULTY adds 10 multicolour cards to the normal game. These cards get marked by ANY colour clue.


5) Intentional Discard - Sometimes players can have hands where all cards are important and unplayable. To tell a player that his hand blocked, discard your '''CHOP''' card when you have the '''LAST CLUE''' ('''always try to give him clue to give and play his hand as fast as it possible''')
== Gameplay ==
You each take turns. During a turn, a player may take one (1) of three actions. After your action, the turn ends and it is the next player's turn.


6) Finesse
The game can end in several ways:


Example 1
#All cards have been drawn from the deck. After this happens, everybody gets 1 more turn. The game ends with the score at the last turn.
Table:
#Your team played all possible cards. In this case, the game ends immediately and you receive the maximum possible score.
R Y G B W M
#Your team made three mistakes that caused misfires. In this case, you lose the game and get negative ten (-10) points.
0 0 0 0 0 0
#Your team 'abandons' the game. Although discouraged, you receive zero (0) points.


XX|XX|XX - me
== Turn ==
During your turn, you have one (1) action. You can choose to do one of the following:


??|??|?? - you
#'''Give a colour or number clue to a teammate:'''  This costs one clue-token (-1). You cannot give a clue if there are zero (0) clue-tokens left. When you give a clue, you must indicate ALL cards of a certain colour, or ALL cards of a certain number.
#'''Play a card:'''  When a card is played, it is evaluated.  If the card fits in one of sequences, it is placed in the appropriate colour stack on the table. If it does not, it is placed in the discard pile and the team gets a misfire-token.
#'''Discard a card:'''  When you discard, the card is placed in the discard pile and you get a clue-token (+1). Note: cards on the discard pile are out of the game and can never return.


5g|2b|4r - 3rd player
When you remove a card from your hand, by either playing or discarding, at the end of your turn, you draw a new card. '''Your newest card is always placed on the left'''.


I clue the 3rd player BLUE color. The card I clued which would normally be played is '''UNPLAYABLE''' and one card would need to be played first. This signals you that you have that card at '''LEFT POSITION''' so you can assume that your '''DRAW''' card is the playable 1b.
== Lingo ==
When you play with others, certain words are used to describe certain objects or situations. Here is a short list.


If your hand contain clued card that could be that needed by color or by number, you should play it, not the left. See example 2.
*'''MARKED''': A card that is highlighted by a clue.
*'''UNMARKED''': A card that is not clued.
*'''CHOP''': The oldest, unmarked card. The right-most card that you have no information on and will chop from your hand.
*'''DRAW''': The newest, unmarked card. The left-most card that you have no information on and was freshly drawn to the left side.
*'''TO BOMB''': A play that causes the third misfire-token. Sometimes called '''EXPLOSION'''
*'''UNIQUE''': A card that has no copy (left) in the deck.
*'''DOUBLE DISCARD''': Discarding the (usually CHOP) card when it can be Unique (or the last copy of the card in the discard pile).
*'''DOUBLE SAVE''': To mark a card that is useless, because the copy of the card is already played, or marked.
*'''STRATEGY''': A set of rules / guidelines / conventions on how to interpret actions by players (including spending of clue-tokens).


Example 2
== ELO rating ==

If you are playing with ELO rating on, your ELO may be changed at the end of the game.

Here is how it works:


??|??|2? - you
#Every player on the team is temporarily considered as having the average ELO rating of the team.
#The system will generate a bot associated with the score your team has achieved (let’s call it '''Hanabot'''). Hanabot’s ELO rating depends on the variant you are playing (50 cards, 60 cards, 60 cards multicolor), the number of players on the team and, most importantly, your team's score. All Hanabot’s ELO ratings have been set by an experienced player, they are not random or simply proportional to the score/number of players.
#Your team (actually your team's average ELO) will now compete against Hanabot. The system will calculate your team’s ELO gain/loss as though your team had tied with Hanabot.


5g|3b|4r - 3rd player
If your score is below 18 (50-card game) or below 21 (60-card game), Hanabot's ELO is always 1000.


Suppose on your last turn you received a 2 clue indicating that you should play the 2y. You now have a clued 2 card still in your hand which you aren't sure you can play. I clue the 3rd player BLUE color. Again, the card I clued which would normally be played is '''UNPLAYABLE''' and one card would need to be played first. You should, in this case, play the 2 card which has already been clued because you have the information on it.

XX|XX|XX - me
The 55-card variant (50 cards + 1 of each value in the sixth color) cannot be played with ELO rating on. This is because this variant is highly dependent on draw and a team’s score may not always reflect the players’ skills.


1g|4b|3w - 2nd player
If you achieve the perfect score and this should cost you ELO points, you will be considered as having beaten the bot associated with the score, so that you lose no ELO points.

To be confirmed: I think the ELO-system has had an overhaul.

== About "cheating" ==
In the "real life Hanabi", you can talk. That's why we chose to let the chat open for the online version.


I clued you RED color. 2nd player will (and does) play his 1 green using the rule of finesse. 2nd player determined that your red is '''UNPLAYABLE''', and trying to fix it, he played the 1g which was not clued. You see that the color of the card played was different from the color of the card you were clued, which gives you the information that the clue you received was a '''BLUFF'''. Now you know that your red card is 2r (or possibly also 2m in very difficult difficulty).
As a consequence, it is very easy to cheat at Hanabi. However, as you can imagine, cheating is very stupid and has no interest... except for ELO boosting. This is why there is no international ranking for this game (ie: best player, second best player) and no trophies associated to it.


8) Reverse
==CONVENTIONS==
If people just play in a very basic way, meaning that they wait until they have received the colour and number to play each card, it is generally difficult to achieve a high score.
Common sense, observation and combination of given information allow to visualize which card(s) should be played according to a single clue (thus saving precious clue-tokens and speeding up the game in order to reach a better score).
However, many players have elaborated conventions in order to codify the sequence of actions and thus simplify the thinking process.


Example 1
In the following section, colours are indicated by their first letter: R - Red, Y - Yellow, G - Green, B - Blue, W - White. For example, 2Y means the card with number 2 and colour yellow.
Table:
R Y G B W M
0 0 0 0 0 0


XX|XX|XX - me
===Most standard convention===
In 4 words : ''Play left, discard right''.


4g|2y|3w - 2nd player
- When a clue designates several cards, it is generally the card furthest to the left that must be played.


??|??|?? - you
Indeed, the new cards arriving from the left, a playable card already in hand would have been indicated earlier whereas it is more likely that one wants to play the freshly drawn.
For example, if a player's hand is (1R, 4Y, 5B, 2Y, 2G), it is necessary and enough to give the clue 2 to make him play his 2Y.


I clued 2nd player YELLOW color which would clue them to play under ordinary circumstances but instead of playing they discarded. This indicates to you that you have a '''PLAYABLE''' yellow '''DRAW''' card. In this case, you should play your un-clued draw card.
In complicated situations where the card to be indicated is neither the leftmost of its color nor the leftmost of its number, two players must complement each other by giving one of the elements each, although this rarely happens.
For example, if a player's hand is (1R, 4Y, 5B, 2G, 2Y), it is necessary to give him both the clue ''Yellow'' and the clue ''2'' to make him play his 2Y.


Example 2
- When a player, having no clue to give nor a card to play, is about to discard, he must discard his card furthest to the right among those without a clue. (the ''chop'').
Table:
R Y G B W M
0 0 0 0 0 0


XX|XX|XX - me
Indeed, the new cards arrive from the left, the cards on the right are older, and therefore less likely to be used since the other players have had more time to say that they should be played if necessary.


??|?y|?? - you
This allows other players to anticipate which cards are about to be discarded and therefore protect them if necessary. So for example, when a 5 (card present in a single copy and therefore particularly valuable) arrives in a player's discard position, the others know that it risks being discarded and therefore give the clue ''5'' to be preserved ('' saving clue ''). It should be understood from the position of the card that it is thus to be preserved and not to be played, paying attention to the cards already discarded (last copy).


1y|2b|3g - 3rd player
In complicated situations where all of our cards have a clue and therefore theoretically no card should be discarded (since cards with clue should not be discarded) and where it is impossible to play, it is preferable to give a clue, even if it is not very relevant.


Example 2 is the same hand from the other perspective.
Obviously, if a player has a card that he is sure he will never be able to play (for example a card on which he has a blue hint when the blue pile has already been completed), such card must be discarded in priority.


Finesse, Reverse, and Bluff help you to save +50% clues, so getting a score of 30 (in the higher difficulties) becomes possible. There are some other variants of these advanced tricks; you situations like reverse for next 3 turns or finesse when 2-3 players have playable cards at the left sides and you just give clue to the last playable card...
===Advanced conventions===
The 3 most classical advanced conventions are: ''finesse'', ''bluff'' et ''reverse''.


9) Positional Discard (endgame) - Sometimes in the last turns you will have no useful cards to play and need to give a clue to indicate to a player which card to play but you have no remaining clues. In this case, discard the card in the same position as the card that you want that player to play.
====''Finesse''====
Table:
- An example is more telling than a long speech: suppose it is player 1's turn and no card has yet been played, nor any clue given:
R Y G B W M
5 5 3 5 5 5


XX|XX|XX - me
1) ?  ?  ?  ?


??|??|3? - you
2) 1B 5Y 3B 1W


1y|2b|5g - 3rd player
3) 5R 2R 2B 2G


In this example, I discard my 2nd card. This indicates to you that your 2nd card is the 4g.
4) 4G 1Y 1R 3Y


10) Having the optimal player draw the last card (endgame) - 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. After the last card is drawn, each player receives exactly one more turn. Sometimes near the end of the game you will want a specific player to play or discard in order to get the last turn. Giving an unusable clue can prevent a player from drawing the last card and begin the last round.
If player 1 gives the blue clue to player 3, it clearly indicates his 2B, while the expected card is a 1B. This means that the card which fills the hole is somewhere upstream, in this case in the hand of player 2. The latter, seeing that indeed the 1B is missing, understands that it is a question of a "finesse" and plays his 1B according to the convention "play left, discard right".


Table:
If the 1B had been in any other position in Player 2's hand, he would have needed a prior clue to know which one. Thus he would have played the card furthest to the left among his corresponding marked cards (in this case a 1 card or a blue card if the 1B and the 5Y had been reversed).
'''1 card remaining in deck - Your turn'''
R Y G B W M
5 5 3 4 5 5


XX|XX|5b - me
Player 3 then only has to play his 2B: two cards have been played thanks to a single clue.


??|??|3? - you
- In situations like the following :


1y|4b|5g - 3rd player
1) ?  ?  ?  ?


In this situation, assume everyone knows where the remaining playable cards are. Instead of discarding in this situation, you want the 3rd player be the one to play and draw the last card. Give any clue to prevent triggering the endgame so that 3rd player can play 4b triggering the endgame and then in their last turn play the 5g.
2) 1B 5Y 3B 3W


== Cards ==
3) 4G 1Y 1R 3Y


In a standard game of Hanabi, there are 5 colors of cards of value 1 to 5. In each suit there are
4) 5R 2R 2B 2G


-three 1s
where player 1 gives a clue ''blue'' to player 4, this can point to either player 2 and 3. To find out which one is designated, each looks at the other's cards. In this case, player 2 sees that finesse cannot be addressed to player 3 since he has a 4G card on the far left and not a 1B. Player 2 therefore plays his own card.


-two 2s
==== '' Bluff '' ====
'' Bluff '' looks like a '' finesse '', except that the player who plays his card is in a way "trapped": he does not play the card he expects from ' 'finesse'.


-two 3s
An example speaks louder than a long speech: suppose it's player 1's turn and no card has yet been played, nor any clue given:


-two 4s
1) ?  ?  ?  ?


-one 5
2) 1W 5Y 3B 3W


== About "cheating" ==
3) 5R 2R 2B 2G
 
4) 4G 1Y 1R 3Y
 
If player 1 gives the blue clue to player 3, it clearly indicates his 2B, while the expected card is a 1B. As before, player 2 then assumes that his leftmost card is a 1B. So he plays it. Surprise, it's a 1W! Player 3 then understands that it is a bluff and DOES NOT PLAY his blue card. However, he knows that it is a 2, and keeps it for later, when he can play it.
 
Unlike "finesse", to avoid any ambiguity, it is better to "bluff" only on the person who follows us immediately in the turn order.


In the "real life Hanabi", you can talk. That's why we chose to let the chat open for the online version.
==== '' Reverse '' ====
'' Reverse '' looks like '' finesse '', except that the player given the clue is located before the one with the card that fills the gap.


As a consequence, it is very easy to cheat at Hanabi. However, as you can imagine, cheating is very stupid and has no interest... except for ELO boosting. This is why there is no international ranking for this game (ie: best player, second best player) and no trophies associated to it.
This convention is riskier because it is sometimes possible that the player to whom the hint is given does not realize that it is a '' reverse '' and plays his card.


== ELO rating ==
An example speaks louder than a long speech: suppose it's player 1's turn and no card has yet been played, nor any clue given:
If you are playing with ELO rating on, your ELO may be changed at the end of the game.


Here is how it works:
1) ?  ?  ?  ?


1) Every player on the team is temporarily considered as having the average ELO rating of the team.
2) 5R 2R 2B 2G


2) The system will generate a bot associated with the score your team has achieved (let’s call it '''Hanabot'''). Hanabot’s ELO rating depends on the variant you are playing (50 cards, 60 cards, 60 cards multicolor), the number of players on the team and, most importantly, your team's score. All Hanabot’s ELO ratings have been set by an experienced player, they are not random or simply proportional to the score/number of players.
3) 1B 5Y 3B 3W


3) Your team (actually your team's average ELO) will now compete against Hanabot. The system will calculate your team’s ELO gain/loss as though your team had tied with Hanabot.
4) 4G 1Y 1R 3Y
If your score is below 18 (50-card game) or below 21 (60-card game), Hanabot's ELO is always 1000.


FYI, you can find all bots' ELO ratings here: http://forum.boardgamearena.com/viewtopic.php?f=3&t=4814
If player 1 gives the blue clue to player 2, it clearly tells him his 2B, while the expected card is a 1B. He might think that it is indeed a 1B, but he sees a 1B in question in Player 3's hand and therefore plays something else (for example, he gives the clue to Player 4). Player 3, as before, seeing that the reverse cannot be addressed to player 4, plays his 1B. In the next turn, player 2 can play his 2B.


==== '' Off discard '' ====
It happens that in his turn a player no longer has a clue token and that a card must absolutely be played, it is then possible for him to discard another card than his card furthest to the right. This move tells the next player to play the card in the same position as the one that was discarded.


Example: it's player 1's turn, there are no more clue tokens, a 1B has already been played and a 2B card has already been discarded (in bold the clues known by the players):


The 55-card variant (50 cards + 1 of each value in the sixth color) cannot be played with ELO rating on. This is because this variant is highly dependent on draw and a team’s score may not always reflect the players’ skills.
1) a? b? c? d? e?


2) 4Y 5R 2R 2B 2'''G'''


A loss (3 Strike tokens) is the same as a score of 0.
3) 2G 1'''B''' 5Y 3'''B''' 3W


Player 1 discards card d? instead of the e? card. This indicates to the player that he must play his card in the same position (therefore 2B), which avoids losing it and thus condemning the blue pile.


If you achieve the perfect score and this should cost you ELO points, you will be considered as having beaten the bot associated with the score, so that you lose no ELO points.
This movement is risky because the discarded card can be important or even blocking for the rest of the game. This movement should therefore only be used if there is no other solution.
It is up to the other players to make sure, before leaving a player without a clue token, that the card he could discard to give this clue is not essential for the rest of the game.

Introduction

Hanabi is a cooperative game. Your goal, as a team, is to build a fabulous fireworks show. You do this by playing the cards in the correct order. However, you cannot see your own cards; you can only see the cards of your team mates.

Final Score Ratings

Points Overall impression
5 or less horrible, booed by the crowd...
6-10 mediocre, just a spattering of applause.
11-15 honourable, but will not be remembered for very long...
16-20 excellent, crowd pleasing.
21-24 amazing, will be remembered for a very long time!
25 legendary, everyone left speechless, stars in their eyes

Card distribution

In a game of Hanabi on NORMAL DIFFICULTY, the deck contains 50 cards. Each has exactly one colour: either Red, Yellow, Green, Blue, or White.

There are 10 cards in each colour:

  • three 1s
  • two 2s
  • two 3s
  • two 4s
  • one 5

Multicolour cards

There are three variants that add a 6th colour: the multicolour.

  1. TRICKY DIFFICULTY adds 10 multicolour cards to the normal game. These cards get marked by a separate multicolour clue.
  2. HARD DIFFICULTY adds 5 multicolour cards to the normal game: one of each number. These cards get marked by a separate multicolour clue.
  3. VERY DIFFICULT DIFFICULTY adds 10 multicolour cards to the normal game. These cards get marked by ANY colour clue.

Gameplay

You each take turns. During a turn, a player may take one (1) of three actions. After your action, the turn ends and it is the next player's turn.

The game can end in several ways:

  1. All cards have been drawn from the deck. After this happens, everybody gets 1 more turn. The game ends with the score at the last turn.
  2. Your team played all possible cards. In this case, the game ends immediately and you receive the maximum possible score.
  3. Your team made three mistakes that caused misfires. In this case, you lose the game and get negative ten (-10) points.
  4. Your team 'abandons' the game. Although discouraged, you receive zero (0) points.

Turn

During your turn, you have one (1) action. You can choose to do one of the following:

  1. Give a colour or number clue to a teammate: This costs one clue-token (-1). You cannot give a clue if there are zero (0) clue-tokens left. When you give a clue, you must indicate ALL cards of a certain colour, or ALL cards of a certain number.
  2. Play a card: When a card is played, it is evaluated. If the card fits in one of sequences, it is placed in the appropriate colour stack on the table. If it does not, it is placed in the discard pile and the team gets a misfire-token.
  3. Discard a card: When you discard, the card is placed in the discard pile and you get a clue-token (+1). Note: cards on the discard pile are out of the game and can never return.

When you remove a card from your hand, by either playing or discarding, at the end of your turn, you draw a new card. Your newest card is always placed on the left.

Lingo

When you play with others, certain words are used to describe certain objects or situations. Here is a short list.

  • MARKED: A card that is highlighted by a clue.
  • UNMARKED: A card that is not clued.
  • CHOP: The oldest, unmarked card. The right-most card that you have no information on and will chop from your hand.
  • DRAW: The newest, unmarked card. The left-most card that you have no information on and was freshly drawn to the left side.
  • TO BOMB: A play that causes the third misfire-token. Sometimes called EXPLOSION
  • UNIQUE: A card that has no copy (left) in the deck.
  • DOUBLE DISCARD: Discarding the (usually CHOP) card when it can be Unique (or the last copy of the card in the discard pile).
  • DOUBLE SAVE: To mark a card that is useless, because the copy of the card is already played, or marked.
  • STRATEGY: A set of rules / guidelines / conventions on how to interpret actions by players (including spending of clue-tokens).

ELO rating

If you are playing with ELO rating on, your ELO may be changed at the end of the game.

Here is how it works:

  1. Every player on the team is temporarily considered as having the average ELO rating of the team.
  2. The system will generate a bot associated with the score your team has achieved (let’s call it Hanabot). Hanabot’s ELO rating depends on the variant you are playing (50 cards, 60 cards, 60 cards multicolor), the number of players on the team and, most importantly, your team's score. All Hanabot’s ELO ratings have been set by an experienced player, they are not random or simply proportional to the score/number of players.
  3. Your team (actually your team's average ELO) will now compete against Hanabot. The system will calculate your team’s ELO gain/loss as though your team had tied with Hanabot.

If your score is below 18 (50-card game) or below 21 (60-card game), Hanabot's ELO is always 1000.


You can find all bots' ELO ratings here: http://forum.boardgamearena.com/viewtopic.php?f=3&t=4814

The 55-card variant (50 cards + 1 of each value in the sixth color) cannot be played with ELO rating on. This is because this variant is highly dependent on draw and a team’s score may not always reflect the players’ skills.

If you achieve the perfect score and this should cost you ELO points, you will be considered as having beaten the bot associated with the score, so that you lose no ELO points.
To be confirmed: I think the ELO-system has had an overhaul.

About "cheating"

In the "real life Hanabi", you can talk. That's why we chose to let the chat open for the online version.

As a consequence, it is very easy to cheat at Hanabi. However, as you can imagine, cheating is very stupid and has no interest... except for ELO boosting. This is why there is no international ranking for this game (ie: best player, second best player) and no trophies associated to it.

CONVENTIONS

If people just play in a very basic way, meaning that they wait until they have received the colour and number to play each card, it is generally difficult to achieve a high score. Common sense, observation and combination of given information allow to visualize which card(s) should be played according to a single clue (thus saving precious clue-tokens and speeding up the game in order to reach a better score). However, many players have elaborated conventions in order to codify the sequence of actions and thus simplify the thinking process.

In the following section, colours are indicated by their first letter: R - Red, Y - Yellow, G - Green, B - Blue, W - White. For example, 2Y means the card with number 2 and colour yellow.

Most standard convention

In 4 words : Play left, discard right.

- When a clue designates several cards, it is generally the card furthest to the left that must be played.

Indeed, the new cards arriving from the left, a playable card already in hand would have been indicated earlier whereas it is more likely that one wants to play the freshly drawn. For example, if a player's hand is (1R, 4Y, 5B, 2Y, 2G), it is necessary and enough to give the clue 2 to make him play his 2Y.

In complicated situations where the card to be indicated is neither the leftmost of its color nor the leftmost of its number, two players must complement each other by giving one of the elements each, although this rarely happens. For example, if a player's hand is (1R, 4Y, 5B, 2G, 2Y), it is necessary to give him both the clue Yellow and the clue 2 to make him play his 2Y.

- When a player, having no clue to give nor a card to play, is about to discard, he must discard his card furthest to the right among those without a clue. (the chop).

Indeed, the new cards arrive from the left, the cards on the right are older, and therefore less likely to be used since the other players have had more time to say that they should be played if necessary.

This allows other players to anticipate which cards are about to be discarded and therefore protect them if necessary. So for example, when a 5 (card present in a single copy and therefore particularly valuable) arrives in a player's discard position, the others know that it risks being discarded and therefore give the clue 5 to be preserved ( saving clue ). It should be understood from the position of the card that it is thus to be preserved and not to be played, paying attention to the cards already discarded (last copy).

In complicated situations where all of our cards have a clue and therefore theoretically no card should be discarded (since cards with clue should not be discarded) and where it is impossible to play, it is preferable to give a clue, even if it is not very relevant.

Obviously, if a player has a card that he is sure he will never be able to play (for example a card on which he has a blue hint when the blue pile has already been completed), such card must be discarded in priority.

Advanced conventions

The 3 most classical advanced conventions are: finesse, bluff et reverse.

Finesse

- An example is more telling than a long speech: suppose it is player 1's turn and no card has yet been played, nor any clue given:

1) ?  ?  ?  ?

2) 1B 5Y 3B 1W

3) 5R 2R 2B 2G

4) 4G 1Y 1R 3Y

If player 1 gives the blue clue to player 3, it clearly indicates his 2B, while the expected card is a 1B. This means that the card which fills the hole is somewhere upstream, in this case in the hand of player 2. The latter, seeing that indeed the 1B is missing, understands that it is a question of a "finesse" and plays his 1B according to the convention "play left, discard right".

If the 1B had been in any other position in Player 2's hand, he would have needed a prior clue to know which one. Thus he would have played the card furthest to the left among his corresponding marked cards (in this case a 1 card or a blue card if the 1B and the 5Y had been reversed).

Player 3 then only has to play his 2B: two cards have been played thanks to a single clue.

- In situations like the following :

1) ?  ?  ?  ?

2) 1B 5Y 3B 3W

3) 4G 1Y 1R 3Y

4) 5R 2R 2B 2G

where player 1 gives a clue blue to player 4, this can point to either player 2 and 3. To find out which one is designated, each looks at the other's cards. In this case, player 2 sees that finesse cannot be addressed to player 3 since he has a 4G card on the far left and not a 1B. Player 2 therefore plays his own card.

Bluff

Bluff looks like a finesse , except that the player who plays his card is in a way "trapped": he does not play the card he expects from ' 'finesse'.

An example speaks louder than a long speech: suppose it's player 1's turn and no card has yet been played, nor any clue given:

1) ?  ?  ?  ?

2) 1W 5Y 3B 3W

3) 5R 2R 2B 2G

4) 4G 1Y 1R 3Y

If player 1 gives the blue clue to player 3, it clearly indicates his 2B, while the expected card is a 1B. As before, player 2 then assumes that his leftmost card is a 1B. So he plays it. Surprise, it's a 1W! Player 3 then understands that it is a bluff and DOES NOT PLAY his blue card. However, he knows that it is a 2, and keeps it for later, when he can play it.

Unlike "finesse", to avoid any ambiguity, it is better to "bluff" only on the person who follows us immediately in the turn order.

Reverse

Reverse looks like finesse , except that the player given the clue is located before the one with the card that fills the gap.

This convention is riskier because it is sometimes possible that the player to whom the hint is given does not realize that it is a reverse and plays his card.

An example speaks louder than a long speech: suppose it's player 1's turn and no card has yet been played, nor any clue given:

1) ?  ?  ?  ?

2) 5R 2R 2B 2G

3) 1B 5Y 3B 3W

4) 4G 1Y 1R 3Y

If player 1 gives the blue clue to player 2, it clearly tells him his 2B, while the expected card is a 1B. He might think that it is indeed a 1B, but he sees a 1B in question in Player 3's hand and therefore plays something else (for example, he gives the clue to Player 4). Player 3, as before, seeing that the reverse cannot be addressed to player 4, plays his 1B. In the next turn, player 2 can play his 2B.

Off discard

It happens that in his turn a player no longer has a clue token and that a card must absolutely be played, it is then possible for him to discard another card than his card furthest to the right. This move tells the next player to play the card in the same position as the one that was discarded.

Example: it's player 1's turn, there are no more clue tokens, a 1B has already been played and a 2B card has already been discarded (in bold the clues known by the players):

1) a? b? c? d? e?

2) 4Y 5R 2R 2B 2G

3) 2G 1B 5Y 3B 3W

Player 1 discards card d? instead of the e? card. This indicates to the player that he must play his card in the same position (therefore 2B), which avoids losing it and thus condemning the blue pile.

This movement is risky because the discarded card can be important or even blocking for the rest of the game. This movement should therefore only be used if there is no other solution. It is up to the other players to make sure, before leaving a player without a clue token, that the card he could discard to give this clue is not essential for the rest of the game.
