Heisenburger is a fun, fast, cooperative card game with limited communication for 2 - 4 players.

Each player has a hand of numbered ingredient cards. Each turn you play a single card from your hand to add toppings to the burger. Cards must be played in ascending order. But because the ingredients are in a quantum state of uncertainty, they must be played face-down and you may not communicate about your hand with the other players.

As each turn progresses, ingredient cards are revealed and players may use special science sauce actions to get more information about the unrevealed cards in the burger and the cards other players have in their hands. But they must hurry. Cards are revealed every turn and each time a card is revealed out of order it is discarded. If this happens three times, the players lose.
