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 firework manufacturers who accidentally mixed up powders, fuses and pockets from a firework display. The show is about to start and panic is setting in. They have to work together to stop the show becoming a disaster! The card deck consists of five different colors of cards, numbered 1–5 in each color. For each color, the players try to place a row in the correct order from 1–5. Sounds easy, right? Well, not quite, as in this game you hold your cards so that they're visible only to other players. To assist other players in playing a card, you must give them hints regarding the numbers or the colors of their cards. Players must act as a team to avoid errors and to finish the fireworks display before they run out of cards.
