Traffic Lights: Signal Flow

You are the traffic light. Every car on the map is waiting for you to decide who goes and who waits.

Tap a signal to turn it green, hold the flow, and get every vehicle home without a single crash. Easy to pick up in the first worlds — then the junctions grow arms, the trains start arriving, the roundabouts fill up, and suddenly you are running a whole city.

WHAT YOU DO

• Tap signals to open and close lanes
• Read the whole board, not just the car in front
• Keep traffic rolling to build the combo multiplier
• Earn three stars by finishing clean and finishing fast

WHY IT GETS HARD

• Some lanes have no signal at all — you cannot stop those, you can only plan around them
• Level crossings close when the train comes, and the train does not negotiate
• Roundabouts, star junctions and multi-arm intersections
• Pedestrians have the right of way. Always. A green light is not permission to drive through someone
• Emergency vehicles will not sit politely in your queue

1,117 LEVELS · 56 WORLDS · 3 ACTS A quiet leafy junction. A night-shift container port. An airport ring road. A desert crossing, a seaside town with a railway running through the middle of it, an open-water causeway after dark. Every world looks different and asks for something different.

BUILT TO BE FAIR

• You only lose a life for something you could actually see coming
• Hints appear once, when the mechanic is new, and never nag you again
• The star gate scales gently — replay any earlier level whenever you want to top up

ALSO

• One-handed play, portrait, no account needed
• Full English and Turkish
• Adjustable speed: slow it down to plan, speed it up to finish
