In the most common "positive" or "race" games, players seek to win as many tricks or card points as possible. To win a hand, a player typically needs to win a minimal number of tricks or card points; this minimal threshold is usually called the "contract", and may be defined by the game's rules (a simple majority of total available points or tricks, or tiered thresholds depending on which player or side has captured certain cards), or the result of an "auction" or "bidding" process. A player who wins more than the number of tricks or card points necessary for winning the hand may be rewarded with a higher score, or conversely (in exact-prediction games) they may be penalized.
