About Ace Machine

Smash, lob and slice your way to glory on a court where the AI never quite catches your shots.

On a computer: Mouse to aim, Left-click to swing; hold longer for power, tap for slice
On a phone: Drag finger to aim, release to swing; short flick for slice, long hold for smash

Enis described this game in a sentence on OhMyGames and the AI built it. You can make your own the same way, free to start.
