This classic party game is perfect for any number of players, but between ten and sixty make for the best game. All the players stand in long lines, except for one player, or parent, who is chosen to be Simon. Simon will instruct the rest of the players to perform certain physical movements, and the players will follow him with that movement, until he suggests another. However, Simon must say “Simon says” before naming the movement in order for the rest of the players to follow along. If Simon omits saying “Simon says” in the command, the rest of the players do not perform the movement, even if Simon is demonstrating it.
Any player who fails to obey Simon's commands promptly, or who obeys commands that are not accompanied by the words “Simon says,” must leave the game. The last player left in the group is the winner.
A variation on Simon says: The leader of the game calls out “Ducks fly,” and raises his arms to represent flying. The players imitate him. He continues, naming any animals he chooses instead of ducks. As long as he names an animal that can fly, the players continue to imitate him; but if he names one that cannot fly—for example, if he calls out “Cats fly”—the players remain motionless.
