General rules for Hanabi:
== Overview ==
<br />The '''CHOP''' card is the un-clued card which is furthest to the '''RIGHT'''.
<br />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'''
Hanabi is a cooperative game where your collective goal is to build a fabulous fireworks show. Like any decent show, you should start with small fireworks and finish with the big ones. You will do this by playing red, yellow, green, blue and white cards from ranks 1 to 5. The problem? You don't know what cards you have. But you know which ones your fellow players do. So you must communicate with each other to build a proper show by placing cards in sequential order with no misfires.


2) Save - Sometimes players can have important cards that are not playable immediately. To save a card, wait until the card is the '''CHOP''' card and clue it '''BY NUMBER'''.
====Cards and Firework Stacks====


3) There are two ways to make somebody play(put/place) a card:
The deck has 50 cards. The cards come in five colors: {{pill|red|firebrick}} {{pill|yellow|gold}} {{pill|green|green}} {{pill|blue|royalblue}} {{pill|white|white}}
  3.1 '''BY COLOR''': when you get or give color clue it means '''LEFT COLORED CARD PLAYABLE''' (unless the clue provides more information on another card)
  3.2 '''BY NUMBER''': when you get or give a number clue it means '''LEFT NUMBERED 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 to 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.
Each color has 10 cards: 3 {{HCard|1|silver}}, 2 {{HCard|2|silver}}, 2 {{HCard|3|silver}}, 2 {{HCard|4|silver}}, 1 {{HCard|5|silver}}.


5) Try not to give unnecessary clues. In advanced play, every clue is played with a purpose behind it.
There is only one firework stack of each color which start empty. {{hTable}}


Advanced Tactics:
Each firework must be placed in ascending order starting from 1, so you are aiming for {{hTable|5|5|5|5|5}}.


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''')
Playing a card on any stack that is not the next number in the sequence will result in a misfire. '''If three misfires occur, the game is over and the players lose.'''


6) Finesse
====Communication====
<code>
<br />Example 1
<br />Table:
<br />R Y G B W M
<br />0 0 0 0 0 0


XX|XX|XX - me
You communicate with your teammates via '''clues'''. You have a limited number of clues, represented by tokens like this: {{Hclue|s=1}}


??|??|?? - you
Each time a clue is given, one {{Hclue|s=1}} moves from the white area (available tokens) to the black (used tokens): {{hClues|s=1.2|a7=}}.


5g|2b|4r - 3rd player
If there are no tokens available, you must play or discard on your turn.
</code>


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.
{{reminder|Do '''not''' give information via chat. That is cheating. If you do, you are dishonored and your reputation as a master pyrotechnician is tainted.}}


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.
==Setup==
<code>
<br />Example 2
<br />Table:
<br />R Y G B W M
<br />0 2 0 1 0 0


XX|XX|XX - me
In a 2-3 player game, each player gets a hand of 5 cards. In a 4-5 player game, each player gets a hand of 4 cards.


??|??|2? - you
==Gameplay==


5g|3b|4r - 3rd player
On your turn, you can do one of three things.
</code>


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.
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Give a clue.</li>
  <li>Discard a card.</li>
  <li>Play a card.</li>
</ul>


7) Bluff
==== Give a Clue ====
<code>
<br />Table:
<br />R Y G B W M
<br />0 0 0 0 0 0


XX|XX|XX - me
To give a clue, there must be at least 1 {{Hclue|s=1}} in the white area.
Select another player's card. You have the choice of telling the player:


1g|4b|3w - 2nd player
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Which cards '''of that color''' the player has</li>
  <li>Which cards '''of that number''' the player has</li>
</ul>


??|??|?r - you
At that point, 1 {{Hclue|s=1}} is moved from the white "available" zone to the black "used" zone.
</code>


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).
The game records these clues, so you can tell which cards other players have pointed out are what number and what color.


8) Reverse
==== Play a Card ====
<code>
<br />Example 1
<br />Table:
<br />R Y G B W M
<br />0 0 0 0 0 0


XX|XX|XX - me
Select a card in your hand and then {{button|Play selected card}} or just drag the card onto the firework stacks in the center to play it.
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>If it '''is''' the next card in sequence for a color, it is automatically placed on the appropriate stack, adding to or completing the firework stack.</li>
  <li>If it '''is not''' the next card in sequence for any color, then the firework has misfired and the card is discarded.</li>
</ul>
A replacement card is automatically added to the left side of the player's hand.


4g|2y|3w - 2nd player
If the played card completes a firework stack, 1 {{Hclue|s=1}} moves from the spent black area to the white available area.


??|??|?? - you
==== Discard a Card ====
</code>


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.
To discard a card, there must be at least 1 {{Hclue|s=1}} in the black area.


<code>Example 2
Select a card in your hand and then {{button|Discard selected card}} or just drag the card onto the discard area to discard it.
<br />Table:
<br />R Y G B W M
<br />0 0 0 0 0 0


XX|XX|XX - me
A replacement card is automatically added to the left side of the player's hand.


??|?y|?? - you
1 {{Hclue|s=1}} moves from the black area to the white area, making it available.


1y|2b|3g - 3rd player
Discarding is a necessary part of the game as you will need to restore {{Hclue|s=1}} in order to clue more cards.
</code>


Example 2 is the same hand from the other perspective.
== Game End ==


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...
There are three ways the game can end:
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>If the players cause 3 misfires (misplayed cards), the game immediately ends and the players lose.</li>
  <li>If all 5 firework stacks are completed, the players have won and are granted a stunning victory with 25 points.</li>
  <li>If the deck is empty, each player plays one more time (including the player who emptied the deck).</li>
</ul>


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.
====Scoring====
<code>
<br />Table:
<br />R Y G B W M

The score is automatically counted as the game progresses, visible in the player panels.

In this example, I discard my 2nd card. This indicates to you that your 2nd card is the 4g.
The only way to score above 25 is to include multicolored cards. See '''Variants''' below.


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.

This is why instead of three 1s and one 5, there are three 5s and one 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.
You '''cannot give color clues''' for black cards. They have no color (who can see a black firework?). So black cards can only be clued with number.


11) Hint to discard - You can hint to a player to discard by giving them an unusable clue (for example giving a 5 clue when that player has no 5 cards). This can be done to have a player discard a card which would normally be included in a clue (example: 1m|1r|3y|4g|1m would be a situation would be a hand which can be a better target for a 1 clue after that player discards AND there is also a potential for the player to draw another 1 card before being clued for 1s)
The game score starts at -5. That's -1 point for every card missing from the black powder stack.

Also known as "The Sumptuous 5". When you play the last card on a firework stack (typically the 5), a bonus tile is randomly selected for immediate use. Bonus tiles have different effects:


-three 1s
<ul class="bulletlist" style="margin:1em 0;padding-inline-start:40px;">
  <li>Gain a {{Hclue|s=1}}</li>

==== Convention Used ====


-two 3s
''Hanabi'' is a game about communication, but there aren't enough {{Hclue|s=1}} to be able to indicate both color ''and'' number of every played card. So to give more information, the team must agree on a set of interpretations for clues, plays, and discards, called '''conventions'''.


-two 4s
If the players use different conventions to communicate, they are sure to lose. You can read more about conventions on the '''[[Tips_hanabi|Tips]]''' page.


-one 5
During game setup, the creator can indicate which convention set the players should use. These are not enforceable, so please respect the convention set that the table creator set.

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


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.
Preset decks are useful for comparing teams/conventions using the same deck. You can select to have no preset deck or choose one of 5 preset decks of the day. These change every day at 0:00 UTC.


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


Here is how it works:
In a two-player game, hand size is 6 instead of 5. In a five-player game, hand size is 3 instead of 4.
 
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.
 
FYI, 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.
 
 
A loss (3 Strike tokens) is the same as a score of 0.
 
 
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.

Overview

Hanabi is a cooperative game where your collective goal is to build a fabulous fireworks show. Like any decent show, you should start with small fireworks and finish with the big ones. You will do this by playing red, yellow, green, blue and white cards from ranks 1 to 5. The problem? You don't know what cards you have. But you know which ones your fellow players do. So you must communicate with each other to build a proper show by placing cards in sequential order with no misfires.

Cards and Firework Stacks

The deck has 50 cards. The cards come in five colors: red yellow green blue white

Each color has 10 cards: 3 card1,with a Hanabi card 1clue,, 2 card2,with a Hanabi card 2clue,, 2 card3,with a Hanabi card 3clue,, 2 card4,with a Hanabi card 4clue,, 1 card5,with a Hanabi card 5clue,.

There is only one firework stack of each color which start empty. cards in the deckredyellowgreenbluewhitemulticolorblack powder

Each firework must be placed in ascending order starting from 1, so you are aiming for cards in the deckred5yellow5green5blue5white5multicolorblack powder.

Playing a card on any stack that is not the next number in the sequence will result in a misfire. If three misfires occur, the game is over and the players lose.

Communication

You communicate with your teammates via clues. You have a limited number of clues, represented by tokens like this: ​ clue tokens

Each time a clue is given, one ​ clue tokens moves from the white area (available tokens) to the black (used tokens): ​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens​ clue tokens1 clue tokens2 clue tokens3 clue tokens4 clue tokens5 clue tokens6 clue tokens7 clue tokens8 clue tokens.

If there are no tokens available, you must play or discard on your turn.

MediaWiki-note-icons.png​Do not give information via chat. That is cheating. If you do, you are dishonored and your reputation as a master pyrotechnician is tainted.

Setup

In a 2-3 player game, each player gets a hand of 5 cards. In a 4-5 player game, each player gets a hand of 4 cards.

Gameplay

On your turn, you can do one of three things.

  • Give a clue.
  • Discard a card.
  • Play a card.

Give a Clue

To give a clue, there must be at least 1 ​ clue tokens in the white area. Select another player's card. You have the choice of telling the player:

  • Which cards of that color the player has
  • Which cards of that number the player has

At that point, 1 ​ clue tokens is moved from the white "available" zone to the black "used" zone.

The game records these clues, so you can tell which cards other players have pointed out are what number and what color.

Play a Card

Select a card in your hand and then Play selected card or just drag the card onto the firework stacks in the center to play it.

  • If it is the next card in sequence for a color, it is automatically placed on the appropriate stack, adding to or completing the firework stack.
  • If it is not the next card in sequence for any color, then the firework has misfired and the card is discarded.

A replacement card is automatically added to the left side of the player's hand.

If the played card completes a firework stack, 1 ​ clue tokens moves from the spent black area to the white available area.

Discard a Card

To discard a card, there must be at least 1 ​ clue tokens in the black area.

Select a card in your hand and then Discard selected card or just drag the card onto the discard area to discard it.

A replacement card is automatically added to the left side of the player's hand.

1 ​ clue tokens moves from the black area to the white area, making it available.

Discarding is a necessary part of the game as you will need to restore ​ clue tokens in order to clue more cards.

Game End

There are three ways the game can end:

  • If the players cause 3 misfires (misplayed cards), the game immediately ends and the players lose.
  • If all 5 firework stacks are completed, the players have won and are granted a stunning victory with 25 points.
  • If the deck is empty, each player plays one more time (including the player who emptied the deck).

Scoring

The score is automatically counted as the game progresses, visible in the player panels.

Artistic impression is determined by the Artisan League of Fireworks Technicians reference scale:

Points Overall impression
0-5 Horrible, booed by the crowd...
6-10 Mediocre, just a spattering of applause...
11-15 Honorable attempt, but quickly forgotten...
16-20 Excellent, crowd pleasing.
21-24 Amazing, will be remembered for weeks!
25-29 Legendary, everyone left speechless, stars in their eyes!
30 Divine, the display outshines the stars!

The only way to score above 25 is to include multicolored cards. See Variants below.

Variants

Colors

Name # of Cards Definition
Normal 5 colors Play with a 50-card deck of 5 colors (red, yellow, green, blue, white) to make 5 firework stacks.
Tricky 6th color (10 cards) Add a sixth color--multicolor--to make a deck of 60 cards and make 6 firework stacks.
Difficult 6th color (5 unique cards) Same as Tricky, except multicolor cards only have one card of each rank:

1 multicolour1,with a multicolour 1clue,, 1 multicolour2,with a multicolour 2clue,, 1 multicolour3,with a multicolour 3clue,, 1 multicolour4,with a multicolour 4clue,, 1 multicolour5,with a multicolour 5clue,

MediaWiki-note-icons.png​This variant is always played in friendly mode because the score depends too much on the luck of the draw to reflect true skill.
Avalanche of Colors Multicolor (10 multicolor cards) multicolor cards are wild, which means these cards are clued by any color.

Black Powder

Ten black cards are added to the deck. Black cards are played in descending order (from black powder5,with a black powder 5clue, to black powder1,with a black powder 1clue,). This is why instead of three 1s and one 5, there are three 5s and one 1.

You cannot give color clues for black cards. They have no color (who can see a black firework?). So black cards can only be clued with number.

The game score starts at -5. That's -1 point for every card missing from the black powder stack.

5 Flamboyants

Also known as "The Sumptuous 5". When you play the last card on a firework stack (typically the 5), a bonus tile is randomly selected for immediate use. Bonus tiles have different effects:

  • Gain a ​ clue tokens
  • Gain a ​ clue tokens and remove 1 misfire
  • Give a color clue to a player for free
  • Give a number clue to a player for free
  • Shuffle a discarded card back into the deck (optional)
  • Play a discarded card (optional)

Convention Used

Hanabi is a game about communication, but there aren't enough ​ clue tokens to be able to indicate both color and number of every played card. So to give more information, the team must agree on a set of interpretations for clues, plays, and discards, called conventions.

If the players use different conventions to communicate, they are sure to lose. You can read more about conventions on the Tips page.

During game setup, the creator can indicate which convention set the players should use. These are not enforceable, so please respect the convention set that the table creator set.
