In the trick-taking game Pass Pass, you need to create temporary alliances and use cunning strategies so that your card's color is in the majority and you can win cards and valuable diamonds. Each round, players start with eight number cards in hand; cards come in four suits. The first player leads a card of their choice, then each other player plays a card of their choice. Whichever color collectively has the highest sum wins the trick. More specifically, whoever played the highest card in this color takes one of the played cards and adds it to their collection; whoever played the second highest card in this color adds the two cards with the lowest values to their collection, then leads the next trick.

After eight tricks, the round ends, and each player scores 1 point for each collected card and 1 point for each diamond on those cards. Additionally, when a player has a set of one card in each color, they score a pass pass. After three rounds, the player with the most points wins except that if a player scores three pass passes, they win the game immediately!
