Simon says "roll the dice!" One player takes the role of the master, rolls the two dice, and reads aloud the results. The other players try to obey those instructions. If anyone can't obey the instruction, doesn't obey it, or falls over while trying then they are eliminated. The last person standing becomes the master for the next game. The two dice are a "question" die and an "action" die. The question die stipulates a condition, and the action tells you what to do if you meet that condition. So, you might roll the two dice and read out "If you are a boy, stand on one foot" or "If your first name contains an A or an I, hold your left arm out straight" or "if you are smiling, stare at either your feet or the ceiling". You have to keep obeying all prior instructions as you execute new instructions. Some actions give players a choice, such as "put your right hand on your head or on your stomach". If such an instruction comes up again later, the players have to pick the option they aren't already doing, and do it instead. All you need are 2 dice to play. You can either create custom dice, or use two differently colored dice and look up the results on a simple table.
