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
