350Sprint across rooftops, stack cubes, and slide rails in this endless runner!
Roof Rails: Color Stack 3D is a rooftop runner where the bar in your character's hands determines how safely you cross each gap. Collect matching pieces along the route to make that bar longer, then use it to slide across pairs of rails suspended between buildings. Obstacles can cut away sections, while careless movement may leave the bar too short for the next crossing. Reaching the finish is only part of the objective: preserving extra length can carry you farther through the final reward section. The game combines simple steering with route planning, encouraging you to balance valuable pickups against dangerous positions near the platform edges.
Guide the runner left and right to collect bar pieces and line up with safe openings. Avoid saws and other hazards that shorten your rail. When you reach a gap, the bar automatically rests across the rails and carries you forward. Preserve enough length to cross every rooftop and improve the finish reward.
