Red Light, Yellow Light, Green Light

Just like the usual "red light, green light" race with a yellow light thrown in.

How to play

 * 1) Choose one person to be the traffic cop.
 * 2) Have all the rest of the players stand at the start, while the traffic cop has his back to the rest of the players.
 * 3) When the cop says "green light", players have to run fast to the finish line.
 * 4) When the cop says "yellow light", players will slow down.
 * 5) When the cop says "red light", he will turn around and the players have to stop at their tracks. If he catches a player moving during a red light, the player gets sent back to the starting line.
 * 6) The first person to get to the finish will take over as traffic cop for the next round.
