Perimeter
Guard your side. Send the balls back.

- Players: 1–8 players; bots fill the empty seats
- Full game: about 4 min
- Quick version: about 1 min
- Easy to pick up
Pong with a side for each player: send the balls back and guard your side. A ball through your side costs a life, and with none left your side turns to stone. Balls come faster and more often as the round goes on, and the last one guarding a side wins.

How to start
- Open Gonfetti on your phone and start a room. Bots fill the empty seats, so you can play right away. Nothing to install.
- Friends join with the room's link or code, each on their own phone, side by side or far away.
- Or put Gonfetti on a TV, laptop or tablet everyone can see: everyone scans the QR code, and their phone becomes their controller. Gamepads and keyboards work too.
How to play Perimeter
Guard your side of the arena: send every ball back.
How you win: a ball through your side costs a life; lose them all and your side turns to stone. The last one still guarding a side wins. The Quick game is one round with 3 lives; the full game is best of three (or five) rounds, 5 lives each unless the setup says otherwise, with power-ups unless they are turned off.
Your side, your paddle
The arena has a side for each player: yours is in your colour, with your shape behind it. Slide your paddle along it to meet the balls.
A ball through costs a life
Your lives are the little shapes behind your side. Lose the last one and your side becomes a wall of stone.
Aim, and punch
The middle of the paddle sends a ball straight back; nearer the ends sends it off at an angle. Punch to send it back much faster.
More balls, faster
A new ball waits in the middle, its arrow showing where it will go. More balls join as the round goes on, and they all speed up.
Power-ups in the full game
When power-ups are on, a ball that passes a token takes it. Split turns it into two balls; Sticky makes the last paddle to hit it catch balls for a while.
