Hanabi is a small box cooperative card game with a unique conceit. Players play the entire game with their cards facing away from them, towards the other players. As such, players have no idea what cards they are holding. In Hanabi players sort through cards representing fireworks, putting them in the correct order to put on a spectacular firework show. Players can give each other simple clues about the cards in other players hands but each clue costs precious time. Players play cards when they think they have the right one at the right time. However, too many mistakes will lead to the fireworks going off and the game ending early.
