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


== card distrobution ==
* Hanabi is a cooperative game. Your goal, as a team, is to build a fabulous fireworks show.
foreach color: 1, 1, 1, 2, 2, 3, 3, 4, 4, 5
* You have to put together fireworks (red, yellow, green, blue and white) by playing each individual colour in series (1 2 3 4 ⇨ 5).
* You cannot see your own cards; you can only see the cards of your teammates.
* You can only communicate with your teammates via '''clues''', '''playing''' and '''discarding''' cards (see below).
* No other communication is allowed.


== Gameplay ==
{|class="wikitable" style="width:auto;" border="2"
You each take turns. During a turn, a player may take one (1) action. After his action, his turn ends and it is the next player's turn. The game can end in three ways:

1) All cards have been taken from the deck. After this happens, everybody gets 1 more turn. You win the game with the score at the last turn.
== Setup ==


2) You have reached the maximum score possible. In this case you win the game with maximum score.

3) You have made three mistakes that caused a misfire. In this game you lose the game, and get 0 points.
== Game play ==


== Turn ==
Players take turns to either:
During your turn, you get one (1) action. With this action you can chose to do one of the following:


1) Give a clue. This costs a clue-token (-1). You cannot give a clue if there are 0 clue-tokens left. When you give a clue, you can indicate ALL cards of a certain colour, or ALL cards of a certain number.
* Give a '''clue'''
* '''Play''' a card, or
* '''Discard''' a card


2) Play a card. When a card is played, it is evaluated if the card fits in the sequence. If it does, it is placed on the table. If it does not, it is placed on the discard pile and you get a misfire-token.
=== Clue ===


3) Discard a card. When you discard, the card is placed on 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.
Possible with at least {{Hclue|1|size=1.5}} available:
* '''All''' cards of a colour, or
* '''All''' cards of a number, or
* '''No''' cards of a colour, ''e.g. "'''Player1''' to '''Player2''': you have no red card"'' or
* '''No''' cards of a number ''e.g. "'''Player1''' to '''Player2''': you have no 5"''


When you remove a card from your hand, by either playing or discarding, at the end of your turn, you get a new card. '''Your newest card is always placed on the left'''.
# The active player selects a card in another player's hand.
# The active player selects a clue option.
# {{Hclue|1|size=1.5}} is moved from 'available' to 'used'.


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


'''CHOP''' The oldest, unmarked card. The right-most card that you have no information on.
# The active player selects a card in their hand.
# The active player selects the 'Play selected card' button.
#* If the played card fits in any of the sequences, it is placed in the appropriate colour stack on the table.
#* If the played card does not fit, it is placed in the discard pile and the team gets a ''misfire'' token.
# A replacement card is drawn.


'''DRAW''' The newest, unmarked card. The left-most card that you have no information on, this will almost always be the left card.
=== Discard ===


'''TO BOMB''' A play that causes a misfire-token. Sometimes also called '''EXPLOSION'''
Possible with fewer than {{Hclue|8|size=1.5}} available:
# The active player selects a card in their hand.
# The active player selects the 'Discard selected card' button.
# The discarded card is placed in the discard pile.
# {{Hclue|1|size=1.5}} is moved from 'used' to 'available'.
# A replacement card is drawn.


'''MARKED''' A card that is highlighted by a clue.
== Game end ==


'''UNMARKED''' A card that is not marked.
The game can end in several ways:
* All cards have been drawn from the deck. After this happens, each player has one more turn. The game ends with the score after the last turn.
* Your team played all possible cards. In this case, the game ends immediately.
* Your team made three mistakes that caused misfires. In this case, all players lose the game and receive -10 ELO points.
* Your team concedes the game. All players receive -10 ELO points.
* A player quits the game. Only the player that quit first receives -10 ELO points. All other players' ELO is unchanged.


'''DOUBLE DISCARD''' Discarding the CHOP card when it can be a copy of the card that was discarded in the last move.
== Conventions ==


'''DOUBLE SAVE''' To mark a card that is useless, because the copy of the card is already played, or marked.
* There are not enough {{Hclue|size=1}} to clue both colour and number of every played card, so the team must agree on a set of clue, play and discard interpretations, known as a convention.
* Many players use different conventions and if teammates have very different clue interpretations, the game becomes unsuccessful.
* Read about some of the most common conventions in '''[https://boardgamearena.com/forum/viewtopic.php?t=26863 this forum post]''' by [https://boardgamearena.com/player?id=84207926 Romain672].
''Note: the BGA list of conventions does not cover all conventions, so please respect the convention the table creator wants to play. This is why there is an option to display the convention for the table.''


'''UNIQUE''' A card that has no copy (left) in the deck.
=== Standard convention ===


'''STRATEGY''' A set of rules / guidelines on how to interpret moves done by players (including spending of clue-tokens).
Players assume:
* Every marked card will be playable at some point.
* The oldest, unmarked (chop) card is safe to discard.
* Cards known to be trash are discarded in priority ''e.g. cards marked blue when the blue stack is completed.''


== Cards ==
==== Play clue ====
In a game of Hanabi on NORMAL DIFFICULTY, there are 5 colours of cards of value 1 to 5. In each suit there are:
-three 1s
-two 2s
-two 3s
-two 4s
-one 5
This makes 10 cards per colour.


There are three variants that add a 6th colour: the multicolour.
* A clue that does not mark a (unique) chop card¹.
1) TRICKY DIFFICULTY adds 10 multicolour cards to the normal game. These cards get marked by a separate multicolour clue.
* Focus is the newest card.
2) HARD DIFFICULTY adds 5 multicolour cards to the normal game: one of each. These cards get marked by a separate multicolour clue.
Priority:
3) VERY DIFFICULT DIFFICULTY adds 10 multicolour cards to the normal game. These cards get marked by ANY colour clue.
# Lead to plays in other hands.
# Lower rank.


== ELO rating ==
==== Save clue ====
If you are playing with ELO rating on, your ELO may be changed at the end of the game.
 
* A (number) clue that marks a (unique) chop card¹.
* Focus is the chop card.
 
¹''Exception: 2 player game with 2+ consecutive saves.''
 
==== Fix clue ====
 
* A follow-up clue on the same hand as an initial play clue.
* Required to change the focus (and prevent a misfire).

}}
 
==== Bad clue ====
 
* Tell a lie ''e.g. a clue that marks {{Hr|2}} as playable without the required {{Hr|1}}.''
* Mark unknown trash or duplicate cards ''e.g. mark '''4'''s in another hand when your hand could have a copy of that '''4'''.''

* Cathy now knows her marked card is the next playable in the sequence ⇨ {{Hr|4}}, because {{Hr|3}} is already marked.
* Bob now knows his marked red card is {{Hr|3}} and he must play it now.
}}
 
=== Finesse convention ===
 
Players assume:
* Standard convention
* Play clues may also include the '''newest, unmarked''' cards in every hand.
 
{{infoBoxes3 |maxWidth=650
|title1=Finesse example
|body1={{Hr}} {{Hy}} {{Hg}} {{Hb}} {{Hw}}
{{cardholder|Bob 🡲|cards={{Hb|1}}{{Hr|5}}{{Hb|3}}{{Hw|1}} }}
{{cardholder|Cathy 🡲|cards={{Hr|5}}{{Hr|2}}{{Hb|2}}{{Hg|2}} }}
 
* Alice to Cathy: this card is blue.
 
{{Hr}} {{Hy}} {{Hg}} {{Hb}} {{Hw}}
{{cardholder|Bob 🡲|cards={{Hb|1}}{{Hr|5}}{{Hb|3}}{{Hw|1}} }}
{{cardholder|Cathy 🡲|cards={{Hr|5}}{{Hr|2}}{{Hb|2|c=}}{{Hg|2}} }}
 
* Cathy now knows her marked card {{Hb|2}} is playable.
* Bob knows that Cathy will bomb her {{Hb|2}} as {{Hb|1}} unless a {{Hb|1}} is played first.
* Bob does not see the connecting {{Hb|1}}, so assumes he has to play it now.
* Bob does not have a marked card that could be {{Hb|1}}, so Bob '''blind plays his newest unmarked card'''.
* {{Hb|1}} successfully plays.
 
|title2=Reversed finesse example
|body2={{Hr}} {{Hy}} {{Hg}} {{Hb}} {{Hw}}
{{cardholder|Bob 🡲|cards={{Hr|5}}{{Hr|2}}{{Hb|2}}{{Hg|2}} }}
{{cardholder|Cathy 🡲|cards={{Hb|1}}{{Hr|5}}{{Hb|3}}{{Hw|1}} }}
 
* Alice to Bob: this card is blue.
 
{{Hr}} {{Hy}} {{Hg}} {{Hb}} {{Hw}}
{{cardholder|Bob 🡲|cards={{Hr|5}}{{Hr|2}}{{Hb|2|c=}}{{Hg|2}} }}
{{cardholder|Cathy 🡲|cards={{Hb|1}}{{Hr|5}}{{Hb|3}}{{Hw|1}} }}
 
* Bob now knows his marked {{Hb|2}} is playable.
* Bob sees the newest, unmarked card in Cathy's hand is of the same colour '''and''' playable now. Bob assumes it is a finesse with the players in reversed order and his blue card is {{Hb|2}}.
 
|title3=Bluff example
|body3=
{{Hr}} {{Hy}} {{Hg}} {{Hb}} {{Hw}}
{{cardholder|Bob 🡲|cards={{Hw|1}}{{Hr|5}}{{Hb|3}}{{Hw|1}} }}
{{cardholder|Cathy 🡲|cards={{Hr|5}}{{Hr|2}}{{Hb|2}}{{Hg|2}} }}
 
* Alice to Cathy: this card is blue.
 
{{Hr}} {{Hy}} {{Hg}} {{Hb}} {{Hw}}
{{cardholder|Bob 🡲|cards={{Hw|1}}{{Hr|5}}{{Hb|3}}{{Hw|1}} }}
{{cardholder|Cathy 🡲|cards={{Hr|5}}{{Hr|2}}{{Hb|2|c=}}{{Hg|2}} }}
 
* Cathy now knows her marked card {{Hb|2}} is playable.
* Bob does not see the connecting {{Hb|1}}, so assumes he has to play it now.
* Bob does not have a marked card that could be {{Hb|1}}, so Bob '''blind plays his newest unmarked card'''.
* {{Hw|1}} successfully plays and the bluff is revealed.
* Before Bob played, Cathy thought her marked card was {{Hb|1}}.
* After Bob plays, Cathy knows her marked card is another valuable blue card.
All conventions interpret Cathy's card as a valuable, not-yet-playable blue card.
 
Some interpretations are more stringent, also must be a ''1-away-from-playable'' {{Hb|2}}.
}}
 
=== Marked card discard ===
 
If a non-trash marked card is discarded it means:
* A copy of that card is already marked in someone else's hand (''sarcastic discard''); or
* A copy of that card must be marked in a future save clue (use with caution); or
* An unmarked copy of that card is playable (''gentleman's discard'')

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.
'''[https://forum.boardgamearena.com/viewtopic.php?t=33785 Rating is visibly hidden around tables]''' with the 7 distinct ELO skill levels:
If your score is below 18 (50-card game) or below 21 (60-card game), Hanabot's ELO is always 1000.
: {{Beginner}} {{Apprentice}} {{Average}} {{Good}} {{Strong}} {{Expert}} {{Master}}.


# '''''Hanabot''''''s ELO is generated from:
#* Final score¹
#* Average team ELO
#* Colour option²
# ELO change is calculated as if tied with Hanabot³.

'''''[https://forum.boardgamearena.com/viewtopic.php?f=3&t=4814 Hanabots' ELO ratings]''' were set by an experienced player - i.e. ratings are not random or simply proportional to score or players' ELO.''
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.
¹''Hanabot's ELO = 0 with scores < 18 (5 colours) and < 21 (6 colours).''


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.
²''+5 card multicolor option is unrated (too dependent on draw to reflect skill).''

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


== About "cheating" ==
³''ELO change with a perfect score is calculated as if Hanabot lost.''
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.
== Cheating ==


* Players can cheat at Hanabi by sharing information via the chat user interface. This is why ranking has been disabled for this game.

Overview

  • Hanabi is a cooperative game. Your goal, as a team, is to build a fabulous fireworks show.
  • You have to put together fireworks (red, yellow, green, blue and white) by playing each individual colour in series (1 ⇨ 2 ⇨ 3 ⇨ 4 ⇨ 5).
  • You cannot see your own cards; you can only see the cards of your teammates.
  • You can only communicate with your teammates via clues, playing and discarding cards (see below).
  • No other communication is allowed.
Final Score Ratings
Points Overall impression
0-5 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!
25-29 legendary, everyone left speechless, stars in their eyes!
30 Divine, the display outshines the stars!

Setup

Deal
# Players 2-3 4-5
# Cards 5 4

8clue tokens clue tokens

Game play

Players take turns to either:

  • Give a clue
  • Play a card, or
  • Discard a card

Clue

Possible with at least 1clue tokens available:

  • All cards of a colour, or
  • All cards of a number, or
  • No cards of a colour, e.g. "Player1 to Player2: you have no red card" or
  • No cards of a number e.g. "Player1 to Player2: you have no 5"
  1. The active player selects a card in another player's hand.
  2. The active player selects a clue option.
  3. 1clue tokens is moved from 'available' to 'used'.

Play

  1. The active player selects a card in their hand.
  2. The active player selects the 'Play selected card' button.
    • If the played card fits in any of the sequences, it is placed in the appropriate colour stack on the table.
    • If the played card does not fit, it is placed in the discard pile and the team gets a misfire token.
  3. A replacement card is drawn.

Discard

Possible with fewer than 8clue tokens available:

  1. The active player selects a card in their hand.
  2. The active player selects the 'Discard selected card' button.
  3. The discarded card is placed in the discard pile.
  4. 1clue tokens is moved from 'used' to 'available'.
  5. A replacement card is drawn.

Game end

The game can end in several ways:

  • All cards have been drawn from the deck. After this happens, each player has one more turn. The game ends with the score after the last turn.
  • Your team played all possible cards. In this case, the game ends immediately.
  • Your team made three mistakes that caused misfires. In this case, all players lose the game and receive -10 ELO points.
  • Your team concedes the game. All players receive -10 ELO points.
  • A player quits the game. Only the player that quit first receives -10 ELO points. All other players' ELO is unchanged.

Conventions

  • There are not enough clue tokens to clue both colour and number of every played card, so the team must agree on a set of clue, play and discard interpretations, known as a convention.
  • Many players use different conventions and if teammates have very different clue interpretations, the game becomes unsuccessful.
  • Read about some of the most common conventions in this forum post by Romain672.

Note: the BGA list of conventions does not cover all conventions, so please respect the convention the table creator wants to play. This is why there is an option to display the convention for the table.

Standard convention

Players assume:

  • Every marked card will be playable at some point.
  • The oldest, unmarked (chop) card is safe to discard.
  • Cards known to be trash are discarded in priority e.g. cards marked blue when the blue stack is completed.

Play clue

  • A clue that does not mark a (unique) chop card¹.
  • Focus is the newest card.

Priority:

  1. Lead to plays in other hands.
  2. Lower rank.

Save clue

  • A (number) clue that marks a (unique) chop card¹.
  • Focus is the chop card.

¹Exception: 2 player game with 2+ consecutive saves.

Fix clue

  • A follow-up clue on the same hand as an initial play clue.
  • Required to change the focus (and prevent a misfire).

  • Note: if a multicolour card is the intended target of a play clue, the clearest clue would be a colour that does not splash any other card.

Bad clue

  • Tell a lie e.g. a clue that marks
    red2
    ,with a
    red2clue,
    as playable without the required
    red1
    ,with a
    red1clue,

Marked card discard

If a non-trash marked card is discarded it means:

  • A copy of that card is already marked in someone else's hand (sarcastic discard); or
  • A copy of that card must be marked in a future save clue (use with caution); or
  • An unmarked copy of that card is playable (gentleman's discard)

Definitions

Basic

Convention: Agreed set of clue, play and discard interpretations. e.g. a number clue that marks the chop card should be interpreted as a unique card save (if there is a unique card of that number).

Strategy: Plan to achieve the highest score. e.g. to mark first copies of cards.

Marked: A card touched by a clue.

Focus: The target card of a clue.

Play clue: Clue that marks a focused card to play.

Playable: A card that can be marked by a play clue.

Trash: A card that can never be played successfully.

Bomb: A play that causes a misfire.

Draw: The newest card in a hand.

Chop: The oldest, unmarked card in a hand.

Unique: The last remaining card of its rank and colour (that can be played successfully at some point).

Save: A (number) clue that marks a chop card to prevent discard.

Prompt: A play clue that causes connecting marked card(s) to play.

Intermediate

Good Touch Principle: All marked cards will eventually be played.

Splash: Additional new colour or rank information of cards that are not the focus.

Locked: A hand with all cards marked without any plays.

Reclue: A repeated clue that causes marked card(s) to play.

Fix clue: Follow-up clue required to change the focus of a play clue (and prevent a misfire).

Discard clue: Clue that marks trash card(s) to be discarded (to prevent a misfire or unwanted discard).

Stall clue: A clue given to avoid discarding.

Finesse: A play clue that causes connecting unmarked card(s) to play.

Bluff: A play clue that causes a non-connecting unmarked card to play immediately.

Bluff seat: The player directly before the player who is bluffed.

Bottom-decked: When the remaining copy of a playable card is too near the bottom of the deck to achieve a perfect score.

Early save: A save clue with a known playable card in the same hand, or does not mark the chop card¹. i.e. a play clue.

Double save: Two consecutive saves in the same hand.

Double discard: Two consecutive players discard copies of the same chop card, resulting in a unique 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).

Sarcastic discard: Discard of a duplicate marked copy of a card in another hand.

Skip / steal: When a player gives a clue that could have been given by one of the skipped players.

Scream discard: An unexpected discard to save a unique card in another hand.

Advanced

Long finesse: A finesse of three or more cards lasting more than one complete round.

Layered finesse: A finesse with unrelated playable card(s) in front of the target card(s).

Scream play: An unexpected chop play to save a unique card in another hand.

Clued misplay: A play clue that causes a misfire to prevent a unique discard in the same hand.

Positional misplay: An unexpected play that marks the same slot position in another hand to play immediately.

Gentleman's discard: Discard of a playable card to play an unmarked copy in another hand.

Play refusal: Instead of playing, a player clues or discards their chop.

Hesitation play: After a play refusal of a playable card, another player may be able to blind play an unmarked card.

Generation discard: An unexpected discard to gain 1clue tokens.

ELO rating

Rating is visibly hidden around tables with the 7 distinct ELO skill levels:

rank Beginner rank Apprentice rank Average rank Good rank Strong rank Expert rank Master.
  1. Hanabot's ELO is generated from:
    • Final score¹
    • Average team ELO
    • Colour option²
  2. ELO change is calculated as if tied with Hanabot³.

Hanabots' ELO ratings were set by an experienced player - i.e. ratings are not random or simply proportional to score or players' ELO.

¹Hanabot's ELO = 0 with scores < 18 (5 colours) and < 21 (6 colours).

²+5 card multicolor option is unrated (too dependent on draw to reflect skill).

³ELO change with a perfect score is calculated as if Hanabot lost.

Cheating

  • Players can cheat at Hanabi by sharing information via the chat user interface. This is why ranking has been disabled for this game.
