Tennis

First to 7 wins. Play solo against the CPU, or grab a friend for a 1 vs 1.

2 players: left uses W and S, right uses the arrow keys.

Move with ↑ ↓ or drag on mobile. Space to serve, P to pause.

How to play Tennis

You control the magenta paddle on the left, the orange paddle on the right is run by the CPU. Move your paddle up and down to bounce the ball back. Each return makes the ball a touch faster and adds to the rally counter. Score when the ball gets past the CPU. First to seven points wins the match. Use the arrow keys, W and S, or drag your finger on the play area on mobile.

Tips

Hit the ball near the top or bottom of your paddle to send it back at a sharp angle
The CPU is a little slower than you, wide angles often beat it
Stay near the middle when waiting for the next ball, you can react in either direction
Long rallies count too, your longest rally is saved as a personal best
