Shot clock
A timing rule that requires the attacking basketball team to attempt a shot within a set number of seconds.
Overview
The shot clock keeps the game flowing by forcing the team in possession to shoot within a limited time. Under FIBA and NBA rules the attacking team has 24 seconds to release a shot that hits the rim; failing to do so is a violation and the ball goes to the other team.
The clock resets when the ball is gained by the other team, and is often set to a shorter period after an offensive rebound. It prevents teams from holding the ball indefinitely to protect a lead.
Key points
- The team in possession must get a shot to the rim before the clock expires.
- A shot-clock violation is a turnover.
- The clock resets when possession changes.
- A shorter reset is often used after an offensive rebound.

- Foul callA foul call is an official's ruling that a player broke a rule of contact or conduct, triggering a penalty such as a free kick, free throw or penalty.
- AdvantageIn many sports, officials let play continue after a foul when stopping would help the offender, so the fouled team keeps the advantage it has gained.
