Traffic Lights: Signal Flow

Red or green? Your call. Your junction.

Rush hour has already started. Trucks are rolling in, an ambulance is coming through, the level crossing is about to close — and all you have is a handful of traffic lights. Go green at the right moment and the city keeps moving. Go green at the wrong one and everything locks up.

Traffic Control: Signal Flow is a one-tap traffic management and junction puzzle game that still makes you think. The rule is simple: get every vehicle across without a single crash.

🚦 SIMPLE RULE, DEEP GAME Tap a light to turn it green. That's it. But let two flows into the box at once and you get a crash — and every crash costs a heart. The more hearts you finish with, the more stars you earn: 3 hearts = 3 stars. No hidden formula, no surprises. What you see is what you score.

🗺️ OVER 1000 HANDCRAFTED LEVELS 56 worlds across a three-act campaign. Start with quiet neighbourhood crossings and work up to multi-arm boulevards, radial star junctions and roundabouts. Every world brings a new mechanic and a new rhythm.

🚂 EVERY LEVEL IS A DIFFERENT PUZZLE

Railway crossings — clear the tracks before the barrier drops
Roundabouts and radial star junctions
Pedestrian crossings — a green light is never permission to drive through a person
Ambulances, fire engines, police — they get priority
Trucks, buses, heavy machinery — slow to start, slow to stop
Ferries, metros and rush-hour surges

🎯 YOU SET THE PACE Switch game speed between 0.5× and 2× at any time. Slow it down when you want to breathe, speed it up once you've mastered a junction. It never affects your stars — this measures skill, not patience.

🏆 KEEP IT FLOWING, BUILD THE COMBO Uninterrupted traffic raises your combo multiplier. A smooth junction doesn't just look good, it scores better too.

🎨 A WORLD WORTH WATCHING Clean, colourful top-down art. Day and night cycles, rain and fog, windmills turning in the breeze, fish moving under the water. Every world has its own palette.
