When a tie-break score is valid

The tie-break settles a set locked at six games each, and its score follows two rules at once: the winner has to reach seven points, and has to finish two clear. When the two collide — six all — play continues until someone leads by two, which allows scores like 12-10 or, in celebrated cases, far beyond.

Type the score and the page checks three conditions: the winner reached at least seven, the margin is at least two, and above seven the margin is exactly two. That last one is what most often slips past: a score like 9-5 is impossible, because the match would have ended at 7-5 before reaching it.

Worth knowing that variants exist with different rules. The ten-point tie-break, used as a deciding set in doubles and at many tournaments, requires ten instead of seven while keeping the two-point margin. And Wimbledon's final-set tie-break now starts at twelve games all. The validation here covers the classic seven-point form.

Frequently asked questions

Why is 9-5 impossible?

Because play ends the instant someone holds seven points with a two-point lead. To reach 9-5, the score would have passed through 7-5 — the moment both conditions were already satisfied and the tie-break was over. Scores above seven exist only when the margin is exactly two.

What is the longest recorded tie-break?

Professional matches have records passing twenty points each side. The most remembered case is Isner and Mahut at Wimbledon 2010, though there the final set had no tie-break and ended 70-68 in games — which is precisely what motivated the rule change years later.

Who serves in a tie-break?

Whoever would receive the next game serves the first point; after that each player serves two consecutive points, alternating. Ends are changed every six points. The rule exists so that the serve advantage does not favour either player over the course of the decider.
