How to play Acecourt — arcade tennis in your browser

Acecourt is a free, arcade-style tennis game that runs entirely in your browser — no download, no account. You play a short singles match against a computer opponent with real ball physics and a serve you actually time. This guide covers the controls, the scoring, the two shot types, spin, and how the AI opponent works.

What is Acecourt?

Acecourt is a real-time tennis game you play with the keyboard on a computer or with touch controls on a phone. It is not a card or turn-based game: the ball arcs, bounces, spins, and can land in or out just like the real sport. The whole match is simulated on your device, so it works offline once the page has loaded and it never sends what you do to a server.

How to play, step by step

1. Pick a difficulty — Easy, Medium, Hard, or Pro — and press Play.
2. Serve. Press Space (or tap the Serve button) once to toss the ball, then press again to strike it. A timing meter sweeps left to right; hitting it in the green sweet zone gives you the most power and the best placement. A perfect strike can rip an ace.
3. Rally. Move to the ball and swing when it reaches you. Get your timing right and you land a “clean hit” that cracks off the strings and streaks across the court.
4. Win the point, then the game, then the short set — and share your result card.

Keyboard: Arrow keys or WASD move; Space or J is a drive (topspin); Shift or K is a lob/slice. Touch: drag the circle on the left to move, tap Swing to drive, tap Lob for a floaty defensive ball.

Shots, spin and the scoring

There are two shots. A drive is your bread-and-butter attacking stroke: topspin pulls it down fast so you can hit hard and still keep it in. A lob floats high and deep, a useful reset when you are pulled out of position. Where you are moving and which side of your body you strike from bias the ball left, centre, or right — there is no precise cursor, it is all feel.

Scoring is real tennis: 15, 30, 40, game. To keep matches quick, Acecourt uses No-Ad scoring — at 40–40 the very next point decides the game. The set is first to four games (win by two); at 3–3 you play a seven-point tiebreak. A serve must land in the diagonal service box, and two faults is a double fault.

How the AI opponent works

The opponent is a real decision loop, not a scripted cheat. Each moment it predicts where your shot will land using the same physics you see, moves to intercept, and then chooses a drive or lob and a target — usually into the open court away from you. Difficulty changes honest things: Easy reacts slowly, moves slower, and misses more; Hard reads the ball early, covers the court quickly, places tightly, and serves with a real ace threat. Pro pushes every one of those dials further — near-instant reactions, a faster sprint, lines it hugs relentlessly, and almost no free errors — so it plays like a wall for anyone who has already mastered Hard. Even Pro never teleports and never reads inputs it could not see — if it beats you, it out-played you.

Tips to win more

• Learn the serve meter first — a well-timed serve wins free points.
• Move early. Start toward the ball before it crosses the net rather than reacting late.
• Hit into the open court. Send the ball where your opponent is not, then be ready for the wrong-footed reply.
• Use the lob when you are stretched wide — it buys time to recover to the middle.
• Do not over-swing. A clean, well-timed drive beats a mistimed haymaker every time.
• Beat Medium comfortably before you try Hard, then Hard before you take on Pro, and chase your best win streak.
