Roundabout: a calm traffic puzzle game

Roundabout is a free traffic puzzle you play in the browser, on a computer or a phone. Houses and buildings appear across a small city map. Draw roads to connect each house to the building of its colour, and keep the traffic moving as the city grows. A run ends when a building waits too long for its visitors. After the first visit it also plays offline, and it can be installed on a phone or computer like an app.

How to play

• Draw roads between houses and buildings of the same colour. Cars find their own way.
• Plain crossings jam when traffic grows. Roundabouts and traffic lights keep junctions flowing.
• Bridges cross rivers, and motorways lift long routes over the streets below.
• Every trip earns coins. Each week, spend them in the shop on more road, bridges, roundabouts or lights.
• Buildings that are served well grow into busy hubs.

Controls

Drag to draw a road. Keys 1 to 6 pick a tool: road, bridge, motorway, erase, roundabout, traffic light. Space pauses, S opens the shop, Esc opens the menu. On a phone, tap the buttons instead.

Cities

• Bali: a small island with a river, where the tutorial starts.
• San Francisco: morning fog slows cars from 4 to 9 o’clock.
• New York: bridge tolls pay an extra coin for every trip across one of your bridges.
• Kuala Lumpur: monsoon showers arrive without warning and slow traffic.
• Bangkok: a canal city where crews build a free bridge every week.
• Dhaka: rush hour, so people ask for trips faster all game long.
• Riverside: a river map that starts with a bridge.

Free to play, no sign-up, and it can be added to a phone’s home screen. Made with TypeScript and PixiJS.
