About This Game

Draw roads. Run the simulation. Fix the traffic.

Draw roads and bridges, connect growing districts, and watch your city come alive. Design efficient interchanges and prevent your city from becoming Jammed.

Draw Your Road Network

Place districts and draw one-way roads and bridges by hand. Every connection changes how traffic moves through your city.

Watch Traffic Come Alive

Start the simulation and watch hundreds of vehicles travel through your network in real time. Efficient roads keep the city moving. Bad designs create bottlenecks and traffic jams.

A Growing City Never Stops

New districts appear as you play. Roads that worked minutes ago may suddenly become overloaded. Redesign intersections, reroute traffic, and keep the city moving.
