Scoring
Real tennis counting
Points inside a game go love, 15, 30, 40. At 40-all it is deuce, and you must win two points in a row: first for advantage, then the game. The first side to your chosen number of games wins the match, so there is no tiebreak and no mercy.
New to all this? The scoring primer explains every call, and the tracker next to it handles a full real-world match.
The CPU is a simple program with randomised mistakes. It does not model any real player, and no real player or tournament appears anywhere on this site.
