Why do basketball games sometimes go to double overtime?

Updated October 2026 · How we answer

Short answerA game goes to a second overtime when the score is still tied after the first extra period. Each overtime is a fixed period, and play continues until one team leads at the buzzer.

Why a tie leads to more overtime

Basketball games need a winner, so a tied score after regulation sends the game into extra time. Each overtime period is shorter than a regular quarter, and the teams keep playing until the score is no longer tied when the period ends.

A second overtime is common in close games because teams often trade baskets late. Free throws or a last-second shot can keep the margin at one or two points, and fatigue can slow the final minutes.

Factors that stretch the game

Timeouts and fouls near the end of a period can extend the action. Teams can use timeouts in overtime as they would in regulation, which affects how the final shots are set up.

A player who fouls out cannot return, so a team can run short of options in later overtimes. Those limits often change the lineup and the pace of play.

  • A tied score at the end of an overtime sends the game to another period.
  • Each overtime period is shorter than a regulation quarter.
  • Timeouts are available in overtime, but the number may be limited.
  • A player who fouls out stays out for the rest of the game.

Common mistakes

  • Assuming overtime is always five minutes for every league and level.
  • Thinking a tie on the final buzzer of overtime ends the game.
  • Forgetting that a fouled-out player cannot return even in later overtimes.
