A shot clock is a countdown timer that forces the team in possession to attempt a shot within a fixed time, preventing stalling and keeping play flowing. The duration varies by sport: 24 seconds in the NBA, 30 seconds in water polo, and varying lengths in lacrosse (introduced to speed up play). Failing to shoot (and, depending on the sport, hit the rim or goal) before the clock expires results in a turnover. The shot clock fundamentally shapes attacking tactics, creating urgency and rewarding efficient ball movement.
