Basketball fouls, bonus & double bonus explained
Bonus is the most misunderstood light on the scoreboard. This guide explains team fouls, personal fouls, when bonus starts in each league, and how to track it on HooperScore without memorizing the rulebook.
Team fouls vs personal fouls
Personal fouls attach to a player. Get too many and you foul out: 6 in the NBA and NCAA men, 5 in NCAA women, WNBA, FIBA and US high school (NFHS). The player must leave and a substitute enters.
Team fouls attach to the team for that period. Every personal foul (except offensive fouls in some rule sets) adds one team foul. When team fouls cross a threshold, the other team enters the bonus — meaning non-shooting fouls now give free throws instead of just the ball out of bounds.
Scorekeepers track both: player fouls for disqualification, team fouls for bonus. HooperScore tracks team fouls per period with automatic Bonus badges so the table never misses the switch.
When does bonus start? League by league
| League | Bonus starts | What it means |
|---|---|---|
| NBA | 5th team foul / quarter | 2 free throws on non-shooting fouls. Resets each quarter. OT: 4th foul. |
| WNBA / FIBA | 5th team foul / quarter | 2 free throws. Resets each quarter. |
| NCAA men | 5th team foul / half → bonus (1-and-1); 7th → double bonus (2 shots) | Bonus = 1-and-1 (miss front end = no second). Double bonus = 2 automatic shots. Resets each half. OT counts toward 2nd half. |
| NCAA women | 5th team foul / quarter → 2 shots | Same as pro: 2 shots immediately, no 1-and-1. Resets each quarter. |
| US High School (NFHS) | 5th team foul / quarter → bonus; 10th → double bonus | Since 2023-24: bonus = 2 shots (no more 1-and-1). Resets each quarter. |
Note: offensive fouls (player control / team control) never award free throws — ball goes to the other team even in bonus. HooperScore still counts the team foul; referees wave off the shots.
1-and-1 vs double bonus vs 2 shots
- 1-and-1 (NCAA men bonus only): Shoot 1 free throw; make it and you earn a second. Miss and the ball is live — anyone can rebound. Pressure is huge.
- Double bonus: Two free throws guaranteed regardless of the first result. Used in NCAA men (7th foul) and old high-school language for 10th foul.
- Straight 2 shots: Modern NBA, WNBA, FIBA, NCAA women and NFHS high school — once in bonus, every non-shooting defensive foul is 2 shots. Simpler for volunteers.
- Shooting fouls: Always shoot — 2 shots on a missed 2-pointer, 3 shots on a missed 3-pointer, 1 shot on a made basket (and-one). Bonus does not change this.
How to track fouls on the table (without panic)
- When the referee blows and signals a number, repeat it out loud: "Foul, blue 23, that's their second."
- Tap + on that team's foul counter in HooperScore. Watch for the Bonus badge to light — announce "Bonus, white shooting two."
- On free throws, add points one by one (+1 per make), not as a lump sum, so a missed second shot stays correct.
- At period end, reset team fouls to 0. Personal fouls carry over — team fouls do not.
Common volunteer mistake: forgetting to reset team fouls at the quarter break and playing an entire quarter in false bonus. HooperScore resets per period when you advance the period — use that button.
Examples scorekeepers see every weekend
- High school, 3rd quarter, home has 4 fouls. Next defensive foul = 5th → bonus, 2 shots. Announce it before they shoot.
- NCAA men, 1st half, defense has 6 fouls. Next foul = 7th → double bonus, 2 shots even if the first misses.
- NBA pickup on HooperScore with default thresholds: 4 fouls is safe, 5th lights Bonus. In OT the threshold drops — check your league setting.
Let the board remember the thresholds
You don't need to memorize this table mid-game. Set your league once and HooperScore lights Bonus / Double Bonus automatically.
