The extra five minute period played when a regulation basketball game concludes in a tie.
Unlike other overtime periods in sports that generally operate on sudden death rules, overtime in the NBA is treated as an additional time period that concludes when the five minute game clock expires. If the game is still tied at the end of the first overtime period, another overtime period begins. This process is repeated until one team is declared the winner. Because of the additional minutes, individual player scores and statistics tend to be inflated, sometimes resulting in career highs. By rule, all personal fouls are carried over to the overtime period, carrying with them any consequences that may result.
The game with the most overtime periods in NBA history took place in 1951 between the Indianapolis Olympians and the Rochester Royals-the final score was 75 to 73.
