In competition, chess games are played with a time control. Time controls are generally divided into categories based on the amount of time given to each player, which range from classical time controls, which allot about 2 hours or more to each player and which can take upwards of seven hours (even longer if adjournments are permitted), to bullet chess, in which players receive less than three minutes each. Between these are rapid chess (ten to sixty minutes per player) and blitz chess (three to ten minutes). Non-classical chess is sometimes referred to as fast chess.[citation needed]
