Hanabi is a cooperative game, i.e., a game where the players do not play against each other but work together towards a common goal. In this case they are absent minded fireworks manufacturers who accidentally mixed up powders, fuses and rockets from a firework display. The show is about to start and panic is setting in. They have to work together to stop the show from becoming a disaster! The pyrotechnicians have to put together 5 fireworks, (1 white, 1 red, 1 blue, 1 yellow, 1 green), by making a series rising in number (1, 2, 3, 4, 5) with the same colored cards.
The 8 blue clock tokens are placed face up on the table. The 4 red fuse tokens are stacked nearby. The 50 cards are shuffled to make a deck and placed face down.
A hand of 5 cards is dealt to each player if there are 2 or 3 players, or a hand of 4 cards there are 4 or 5 players. Each player DOES NOT see the cards which are dealt to them; the other players do.
On his turn, a player must complete one, and only one, of the following three actions (and he is not allowed to skip his turn):
When carrying out this task, a blue token is used. Used tokens are placed on side, denoting that they have been used. This action cannot be performed if there are no unused blue tokens. In this case, the player has to choose to perform a different action.
Two types of information can be given, and the player giving the information chooses only one type to give:
To carry out this action you must either:
This act RETURNS a used blue token to the unused state. Discarded cards are placed in the discard cards pile. After discarding, a new card from the deck is added to the player's hand. This action cannot be performed if all the blue tokens are on the available (unused).
To carry out this action you must click on the red cross of one of your cards.
The player takes a card from his hand and plays it to the table. Two options are possible:
To carry out this action you must click on the green check of one of your cards.
There can only be one firework of each color. The cards for a firework have to be placed in rising order (1, 2, 3, 4 and finally 5). There can only be one card of each value in each firework (so 5 cards in total).
When a player completes a firework, i.e., successfully plays the card with a value of 5, a used blue token is made available again. This is made for free; the player does not need to discard a card. This bonis is lost of all the blue tokens are already on the table.
There are 3 ways to end a game of Hanabi:
The score is calculated by adding up the largest value card for each firework.
