Discuss your strategy at the beginning of every round. For example, “We really need to get rid of that plane,” or “Let’s make sure we advance 2 spaces.”
You are not allowed to discuss the dice. Saying things like, “If you get a 6, put it here,” or “Use your weakest die to do this action,” is not allowed. Once you have finished discussing, roll all 4 of your dice behind your screen so the other player can’t see them. From this moment on, both players must be completely silent until the end of the round, except for correcting possible rule errors.
REROLL
You can spend a Reroll token at any time during the round. See rule: Reroll.
