- Setup. 4 players, 7 cards each. One extra card is flipped — its suit is trump.
- Bid. In turn, each player declares EXACTLY how many tricks they'll win. The last bidder may NOT make the total = number of tricks (the "hook").
- Play. Follow suit if able. Trump beats non-trump. Highest of led suit wins otherwise.
- Score. Made bid EXACTLY → 10 + bid. Otherwise 0.
