Deuce rules
Advantage vs no-ad tennis scoring
Last updated 5 October 2026
At 40–40 the match either stretches into advantage or ends on the next point. Knowing which rule you are playing — and setting it before the first serve — prevents the most common scoreboard argument in recreational tennis.
The short version. Advantage: from deuce you must win two points in a row. No-ad: the next point wins the game. Tennismatic lets you pick either rule when you set up the match on iPhone or Apple Watch.
What deuce means
In a game, points go love → 15 → 30 → 40. When both sides reach 40, the score is deuce. From there the rule you agreed decides whether the game can end on the next point.
Tournament regulations sometimes fix the rule for you. Club and social matches usually choose before they walk on.
Classic advantage scoring
Advantage is the longer path:
- Win the point at deuce → you have advantage.
- Win the next point → you take the game.
- Lose the next point → back to deuce, and the cycle continues until one side leads by two.
No-ad scoring
No-ad compresses the ending:
- At deuce, the next point decides the game immediately.
- There is no advantage step and no returning to deuce.
- Receivers may still follow any club convention about who receives the deciding point — agree that verbally; the scoreboard only needs the winner of the point.
No-ad is common in doubles leagues and time-boxed club sessions because it caps how long a single game can run.
Which should you pick?
Choose advantage when you want the classic rhythm and do not mind longer games. Choose no-ad when courts are booked in tight slots, you are playing round robins, or the group prefers decisive endings.
Either way, set the rule once in the match setup screen so every deuce follows the same path.
How Tennismatic handles it
During setup, pick Advantage or No-ad under At 40–40. While scoring, keep tapping the side that wins each point at deuce — the engine applies your chosen rule. Undo still works if someone calls the point wrong.
