SET! multiplayer

SET Multiplayer

The classic pattern-matching card game, played live with friends. No accounts, no downloads, no waiting.

Spot the SET before anyone else does. Race 1–3 friends in a private room, call out a SET in real time, and see who has the sharpest eyes.

How to play

Each card has four features: number, shape, shading, and color. A SET is three cards where, for each feature, the cards are either all the same or all different.

Spot one, hit SET, then pick your three cards before the clock runs out. A valid SET scores +10. A wrong guess costs −5, if penalties are on. The game ends when the deck runs out and no SETs remain, and the highest score wins.

Good to know

The game server runs on a free hosting tier. If nobody has played for a while, the first connection can take 30–60 seconds to wake up. After that it's instant.
