A form of estimation whist, with three colored suits (cards from 1 to 20), and the possibility of trumps or no-trumps. You have to bid for which suit (or suits) you think you will capture most cards of, or you can bid to capture fewer cards than anyone else. Get it right, you score get it wrong, you take a penalty. The number of cards per hand increases round by round, and the number of rounds depends on the number of players. - BoardGameGeek
