Zwikken is a Dutch betting game played with a twenty-card deck of traditional playing cards: AKQJT in four suits. Ante, deal three cards each, and turn the top card for the trump suit. The player to the left of the dealer opens bidding. The high bidder leads any card. Cards are played according to these rules of precedent: 1. Play any card of the suit led. 2. Beat all trumps in play. 3. Play any trump. 4. Play any card. Highest trump wins the trick. Otherwise it goes to the highest card of the suit led. The winner leads the next trick. Aside from a couple rules complications, the high bidder either (A) wins the pot by collecting two of three tricks or (B) loses and doubles the pot for the next round.
