Red Light Green Light Timer

Red Light Green Light without a caller: the timer runs six green-light "go" stretches of different lengths with a red-light "freeze" between each, and shuffles their order every round — so the freezes never land where you expect, exactly like a caller who keeps changing the rhythm. It calls each light out loud — "green light," "red light" — the moment it changes, so nobody has to be the caller.

It is a favorite for PE classes, parties, and burning off energy: move on green, freeze on red, and anyone caught moving on a red light is out or goes back to the start. Open the preset in the editor to add rounds, change the freeze length, or adjust the green stretches for a faster, harder game.

Frequently Asked Questions

How does this Red Light Green Light timer work?
It runs six green-light intervals of different lengths with a red-light freeze between them, and reshuffles their order every round, so the freezes are unpredictable — the job a caller usually does. It calls "green light" and "red light" out loud as each one changes; players move on green and must hold still on red.
What are the rules of Red Light Green Light?
Players move toward a finish line on a green light and must freeze the instant it turns red. Anyone caught moving on a red light is sent back to the start (or out); the first to the line wins. The timer calls the lights so everyone can play.
Can I make the game faster or harder?
Yes — open the preset in the editor and shorten the green stretches or the freezes for quicker, trickier rounds, or add rounds to make the game last longer.
