Trump Suit
Trump Suit is a trick-taking card game played by two to three players.. It is played as a solo/”cutthroat” game. The object is to take at least the number of tricks (also known as books) that were bid before play of the hand began. Trump Suit is considered to be an alternative to the traditional card game of Spades, but without the need of four players. Trump Suit is a descendant of the Whist family of card games, which also includes Spades, Bid Whist, Tarneeb, and Oh Hell. Its major difference as compared to other Whist variants is that, instead of trump being decided by the highest bidder from cards in hand, random cards drawn from the leftover, draw deck determines the trump.
