Rules that decide games
Fouls and free throws
4 min
A foul is illegal contact. How fouls are punished is one of the most important — and most bet-relevant — parts of the game.
Personal fouls
When a defender makes illegal contact, the referee calls a personal foul. If the foul happens while a player is shooting, the shooter gets free throws (one for each point the shot would have been worth). Fouls also accumulate against each player: reach a limit (5 or 6 depending on the league) and that player fouls out and cannot return.
Team fouls and the bonus
Teams also rack up fouls each period. Once a team commits enough team fouls, the opponent enters the bonus (or penalty) and shoots free throws on every subsequent foul, even non-shooting ones.
Why this matters late in games
In the final minutes, a losing team often fouls on purpose to stop the clock and force free throws, hoping the opponent misses. This is why close games slow to a crawl at the end, why points spike in the last two minutes, and why a poor free-throw shooting team can blow a lead. It is one of the clearest examples of rules directly shaping a final score.
