シュレディンガーの宴 ("Schrodinger's Banquet") is a card game about quantum mechanics.
Players compete for scoring by dividing into two teams, white cats and black cats. However, the players do not have a set team at the beginning of the game. Players work toward the final victory, while also building the two piles and earning their score.
A a turn, the player simply puts one out of three cards in front of someone. Wherever the card is played, the probability of the black cat team or the white cat team written on the card will be added. If this probability exceeds 100%, the player's team is confirmed. Then, when the player's team is confirmed, the points from the card that confirmed the team will be added to the team. The game is over when all players have a confirmed team, or the deck runs out. The team with the most points wins. Even though it is very simple, frustration is bound to happen.
