Choose one player to be the caller or “it”
Mark a starting line and a finish line
All other players line up at the starting line
The caller stands at the finish line or facing the players
The caller says “Green light” to let players move forward
The caller says “Red light” to make players stop immediately
Any player caught moving after “Red light” must go back to the starting line or follow the agreed rule
Players keep alternating between moving on “Green light” and stopping on “Red light”
The first player to reach the finish line wins
The winner becomes the caller for the next round or the game restarts
