3x3 Basketball Shot Clock (12 Seconds)
A free online 12-second shot clock for FIBA 3x3 (3v3) basketball — the fast, half-court game that became an Olympic sport at Tokyo 2020. The clock above is already set to 12 seconds; press Space to start and stop, or hit reset for a fresh possession.
How long is the 3x3 shot clock?
FIBA 3x3 runs on a 12-second shot clock — exactly half of the 24 seconds used in 5-on-5. The shorter clock keeps the single-basket, half-court game relentless: teams play to 21 points or the highest score after 10 minutes, scoring one point from inside the arc and two from beyond it, with three players a side plus one substitute.
No 14-second reset — just a fresh 12
Unlike 5-on-5, 3x3 has no separate partial reset (there is no 14-second equivalent). A team simply gets a fresh 12 seconds when it gains a new possession, and the clock starts the moment the team gains control of the ball. After a change of possession the team must also clear the ball behind the two-point arc before it can score.
