· How It Works ·
The Clock That Shapes Every Possession
The shot clock gives the team with the ball a fixed amount of time to attempt a shot that touches the ring — 24 seconds in FIBA, NBA, and WNBA basketball. It keeps the game moving, it shapes every offensive set a coach designs, and it is run by a table official who has to make a decision almost every time the ball changes hands, hits the ring, or goes out of bounds.
That job is harder than it looks. Start too early on a throw-in, reset to 24 when the rule says 14, or miss a ball that only touched the backboard, and the whole arena sees the mistake on the display. Most new operators meet a real console for the first time at a real game. ShotClock Pro exists so they do not have to: you can rehearse every start, stop, and reset in your browser, alongside a live or televised game or a recorded game on YouTube, until the decisions become automatic.
Referees use it to sharpen their feel for possession timing, coaches use it to run realistic scrimmages, and fans use it to understand what they are watching. Start with the operator handbook, or dive into one of the guides below.
