Mushroom Sort is a Poker-like set collection and deduction game in which players compete to brew the best mushroom soup.

The game played with 32 mushroom cards divided into 4 colors with values ranging from 1 to 8. A unique feature of the cards is that the color is visible on the back, allowing players to make predictions about card values. At the start of a round, each player is dealt a number cards from the deck and must choose one of them to place face down in the center of the table. The other cards are placed in the player's tableau, also face down. Finally, the players are each dealt one more card to become their starting hand.

Players then take turns choosing a card from another player's tableau and placing a wooden token on it to indicate ownership. The final token can also be placed on one of the central cards. After all tokens have been placed, selected cards are added to the corresponding players' hands, which are then evaluated.

The hand's strength is determined similarly to Poker (Pair, Straight, Full House, etc.) and players with the strongest and the second strongest hands score points. After playing a number of rounds equal to the number of players, the player with the highest total score wins the game.
