Hanabi is a cooperative game where you create a firework show by placing the cards in the right order. Your goal is to organise all the suits of cards in ascending order like Solitaire. The twist is that only other players can see your cards and you have to buy clues from them.

You play the game with a deck of cards of five colours, numbered 1–5. You deal each play a set of cards equal to the number of players in the game. However, you face the cards in your hand towards other players so you can't see them. The aim is to help each other with clues so you can determine your cards and then place them in the middle in colour groups of ascending order.

On your turn, you either play a card, discard a card and draw another or ask for a clue. Clues can only tell you either how many cards of a number you have or how many cards of a colour you have. In this way, you build a picture of your hand and can start to take a risk of placing cards on the table.

The first card for each pile needs to be the number 1 card for each colour. If you place a card that is the incorrect colour or not the next number you use up one of the fuse tokens and once they are gone you have failed the game. The final twist is that there are only a few 1 cards and a single 5 card in the deck, and to get the maximum score you need to find these.

The result is a communication and memory challenge. As you get information about your hand, you not only need to process those implications but also remember what was said. This leads to adjusting how your cards are orientated in your hand to help you remember.
