In the card game contract bridge, the major suits are spades and hearts . The major suits are of prime importance for tactics and scoring as they outrank the minor suits while bidding and also outscore them (30 per contracted trick for major suits—compared to 20 for minor suits). Much of the tactics of bidding in bridge revolves around the attempt by partners to find a "fit" in one of the major suits that will allow them to easily make a game contract. Of the two major suits, spades rank higher than hearts.
