The electronic game Simon is named for Simon Says. However, at least in some versions, it is allowed for Simon to eliminate players by asking them to do something seemingly unrelated to the game (example: "Anyone remaining join me up here."). It is considered cheating to give impossible commands ("Simon says, lift both of your legs up and keep them there!") or phrase the commands in such a way that the other player has no option but to 'go out' ("Simon says, jump up. Arms up." Anyone ending with their arms up is eliminated, because a command that doesn't begin with "Simon says" cannot be obeyed. There can be very complex and difficult command chains, such as "Simon says: Arms up. Often, anyone who speaks is also eliminated. Anyone who breaks one of these two rules is eliminated from the remainder of the game. A command without the beginning "Simon says" means do not do this action.
Players are eliminated from the game by either following instructions that are not immediately preceded by the phrase, or by failing to follow an instruction which does include the phrase "Simon says". One player takes the role of "Simon" and issues instructions (usually physical actions such as "jump in the air" or "stick out your tongue") to the other players, which should be followed only when prefaced with the phrase "Simon says". Simon Says (or Simple Simon Says) is a children's game for three or more players.
