How Twenty-Nine works
- 32 cards (7 to Ace), four players in two teams. Card order: J, 9, A, 10, K, Q, 8, 7. Points: J = 3, 9 = 2, A = 1, 10 = 1, others 0: 28 points in all.
- You first get four cards and bid (16 to 28) how many points your team will win. The highest bidder secretly chooses the trump; four more cards are dealt.
- Play 8 tricks, following suit. Trump stays hidden. A player who cannot follow suit may press Show trump (then must play trump if they have it) or play any card.
- After your team has won a trick, a player holding the King and Queen of trump can declare a pair: the bidder’s target drops by 4 if the bidder’s team declares it, and rises by 4 if the other team does.
- The bidder’s team scores +1 if it reaches the target, otherwise −1. The match ends at the chosen plus or minus score.
