Pong needs no tutorial, so Hand Pong gets straight to it: raise a hand and your paddle rides up and down with it. Take the CPU on solo, or wave a second person into frame for local head-to-head. Either way, first to seven wins.
One-player mode puts a computer paddle on the far side of the court. It reads where the ball will cross its own line, including bounces off the top and bottom, and slides to meet it — but it has a top speed and it aims imperfectly, so it can be beaten. The way to beat it is angle, not power: catch the ball off the end of your paddle to throw it wide, and the CPU runs out of court before it runs out of reach. Either hand works, anywhere in the frame; the game locks onto whichever one is nearest your paddle's current height.
Two players share one webcam, standing side by side. The frame splits down the middle: each player's hand controls the paddle on their own side, cyan versus pink, both live simultaneously. Score when the ball escapes past your opponent; after a short beat the serve relaunches toward whoever just conceded, at a random angle. First to seven takes the match, then a rematch is one button away.
Where the ball meets your paddle matters: contact near the paddle's edge adds spin and sends the ball off at a sharper angle, while the center returns it flat. Combined with the five percent speed-up per hit (capped, and reset on each serve), every exchange gets twitchier the longer it lasts. The paddle follows the middle of your whole hand through a jitter filter, so relaxed, deliberate movements track better than frantic ones.
Start with Control instead of Motion and the game never asks for the webcam. On a keyboard, the arrow keys move your paddle in solo, and in two-player the arrows and WASD take a side each. On a phone or tablet, drag anywhere on your half of the screen. A mouse works too — the paddle simply follows the cursor's height.
Paddle control is vertical movement only, with smoothing that tolerates a wobbly hand. The pause button freezes the match and resumes on a three-second countdown, and the game pauses itself if you switch tabs or rotate the device. Sound is two short effects — a paddle hit and a wall bounce — with an on/off toggle in the pause menu, and there is no music. The camera feed behind the court can be hidden entirely. Scores last only for the match; this cabinet does not post to the arcade leaderboard. On phones it plays in landscape.
All hand tracking happens in your browser, on your device, and no camera footage ever leaves it. Control mode skips the camera altogether. See the privacy policy for the full details, and the play space guide for framing two players on one camera.
Yes. Solo is a full match against a CPU paddle, first to seven, at one fixed difficulty.
No. Two-player is local only: one webcam, one screen, two people standing side by side.
Yes. Start with Control for keyboard, mouse or touch input; the game never requests camera access in that mode.
