Thirty One is a classic card game where you swap and hold cards to build the highest same suit total and win quick, competitive rounds.
Draw from the deck or the discard pile on your turn. Keep up to three cards aiming for 31 in one suit. Swap weak cards for stronger ones in the same suit. Knock when you think your hand can beat the table, or keep drawing if you need more value.
Tip Aim for high cards in one suit and knock early when your hand is strong to pressure opponents.
