How to play

  1. 1. Situation

    You both start with a stake. Whatever you send to them is multiplied.

  2. 2. Your move

    If you send, choose how much of your stake to pass on. If you receive, choose how much of the grown pot to return.

  3. 3. Scoring

    Sending can make you both richer — but they do not have to send anything back.

You each start with 10. What you send is multiplied, then they choose how much comes back.
Your role
Rounds

Opponent. Reciprocal — Returns enough that you both walk away even on the gains.
