Gamehelphanabi

Overview

• Hanabi is a cooperative game. Your goal, as a team, is to build a fabulous fireworks show.
• You have to put together fireworks by playing each individual colour (red, yellow, green, blue and white) in series (1 ⇨ 2 ⇨ 3 ⇨ 4 ⇨ 5).
• Each colour in the deck has 111, 22, 33, 44, 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!

Note: 25 is the maximum score with Normal: 5 colors.

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.

• Tell a lie e.g. a clue that marks

  r

  as playable without the required
  red1

  r

  ,with a

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:

 Beginner  Apprentice  Average  Good  Strong  Expert  Master.

1. Hanabot's ELO is generated from:
   • Final score¹
   • Average team ELO
   • Colour option²
2. ELO change is calculated as if tied with Hanabot.

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).

Cheating

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