Tap a light to turn it green and let the cars go. Every car that gets home earns points. Keep the happy meter full — and give a green to only one street at a time!

Your lights

Tap one to change it. The number shows how many cars are waiting.

Happy meter

Cars that wait a long time start honking and the meter goes down. Keep it full and the whole town stays happy!

How to play

🟢
Green means go. Cars wait at a red light and drive when you give them a green.
🚧
One street at a time. If both streets are green, two cars bump in the middle and a little cone truck has to tidy up.
🟡
Yellow means slow down. When you turn a green off it goes yellow first, so cars that are nearly there can finish crossing.
📣
Waiting is no fun. Cars stuck for ages hold up a honk sign — give them a green before the happy meter runs out.
