Pairs is a “New Classic Pub Game” designed by James Ernest and Paul Peterson. You can play with 2 to 8 players, the rules are very simple, and each game takes about 5 minutes.
Pairs is a press-your-luck game. Each round, players take turns deciding whether to take a card or fold. Folding gets you some points, but catching a pair could get you a lot more points (and points are bad.) The first player to reach a target score loses the game.
