Tap as fast as you can when the light turns green!
| Wait for green | The light holds on red for a random time. |
| Tap | React as soon as it turns green. |
Traffic Light is a reaction game built around a rule every child already knows: red means stop, green means go. Wait for the light to change, then tap as fast as you can. Go early and the round is void, which is a gentler version of exactly the lesson the rule exists to teach.
It works as a game and quietly as road-safety practice. Children learn that waiting for green is not optional and that jumping the light costs you, which is a far more memorable way to absorb the idea than being told. The reaction time it reports gives them something to beat as well.
Do not try to guess when the light will change. The wait is randomised specifically so that anticipating fails, and jumping early voids the round exactly as it should.
Keep your finger near the screen. A large part of a slow time is simply the distance your hand travels, which has nothing to do with how quickly you noticed the change.
Talk about why waiting matters. For a young child, connecting the game rule to real crossings makes the point stick, and the void round is a safe way to experience the consequence.
Take several turns and look at the pattern. A single reading bounces around, but your typical time across a handful of rounds is a fair measure of your reactions.
The round is void and you have to start again, which is the whole point of the game.
Most people land between two and three hundred milliseconds. Children are often a little slower and improve quickly.
Gently, yes. It reinforces the red-means-stop rule while being a genuine reaction test.
From about four, since it needs no reading and only one action.
