Ways to play

The same puzzle, against a real person

In a duel, you and another player solve exactly the same puzzle. The faster time wins, or, in scored games, the higher score.

  • ⚔️

    Duel a stranger

    Your opponent is a real person who played that same puzzle. You see each other only as an animal.

  • 🏟️

    The Arena

    Three rounds, three strangers, one after another.

  • 🔑

    Play with friends

    Send a code. Everyone who has it plays the same puzzle, and you all see how everybody did.

  • 🤖

    The machine, or on your own

    Play the machine, and the app tells you when you are. On your own, there is no clock against anybody.

No accounts, no names.

Other players see you only as an animal picture. There is no chat.
