Basketball Scoreboard & Shot Clock
Run a basketball game with +1/+2/+3 scoring, team fouls with a bonus indicator, an independent 24/14-second shot clock capped to the period clock, and a buzzer the instant either clock hits zero.

How to play
- Enter both team names, pick the period length and whether you're playing quarters or halves, then tap Start Game.
- Tap Start Clock to run the period timer — the shot clock starts alongside it and counts down independently.
- Use +1/+2/+3 under each team to log baskets, +Foul to track team fouls (a BONUS flag appears once a team hits the threshold), and Timeout to log timeouts — none of these touch either clock.
- Tap Reset 24 after a change of possession or Reset 14 after an offensive rebound; both resets are automatically capped so the shot clock never shows more time than remains in the period.
Pickup and rec-league basketball games rarely have a working shot clock, so possessions drag and nobody agrees when a reset should happen. This scoreboard runs a period clock and a fully independent 24-second shot clock side by side, with a dedicated 14-second reset button for offensive rebounds — and the shot clock is automatically capped so it never shows more time than is actually left in the period. Score with dedicated +1, +2 and +3 taps per team, track fouls with an automatic bonus flag once a team reaches the foul threshold, and log timeouts, all without ever nudging either clock. The shot clock buzzes the instant it hits zero, and the period only advances once the game clock has actually run out.
Frequently asked questions
- Why is the shot clock capped instead of always showing 24 or 14?
- If only, say, 9 seconds remain in the period, resetting the shot clock to a full 24 would be misleading — the period ends before the shot clock could ever run out. This scoreboard checks the period clock's remaining time on every reset and caps the shot clock to whichever is smaller, so it always reflects what's actually possible.
- What does the BONUS flag on the foul counter mean?
- Once a team's tracked fouls in the current period reach the bonus threshold, the scoreboard shows a BONUS label next to that team's foul count as a reminder that the opposing team should be shooting free throws on subsequent non-shooting fouls, matching common bonus-foul rules used in most leagues.
- Do the score buttons ever affect the clocks, or vice versa?
- No. Scoring, fouls, and timeouts are tracked completely separately from the period clock and shot clock — tapping +2 or +Foul never starts, pauses, or resets either clock, and running or resetting the clocks never changes the score. This separation is deliberate so a busy scorekeeper can't accidentally corrupt the clock while chasing a fast-breaking game.
