Tip

Pick any two cards. Only one card in the whole deck completes them, so look for that one.

Playing Onset

  1. 1

    Join on your screen

    Start a game, or join one with its room code, link or QR, then pick a name and a color.

  2. 2

    Look for a Set

    Twelve cards go up on every player screen, and on the big screen if you use one. Everyone sees the same cards at the same time.

  3. 3

    Tap SET!

    Tap SET! on your screen, then pick the three cards within 15 seconds. Nobody else can call while you pick.

  4. 4

    Score

    Right: +1 and the three cards are replaced. Wrong or out of time: −1, but never below 0 and you're locked out for 15 seconds.

No Set on the table?

Anyone can call No Set. If the others agree within 15 seconds, three more cards go down.

End of the game

The game ends when the deck runs out, or when someone reaches 5 points in a quick game. Most points wins.
