899u

899u is a sky-bound railway puzzle set among floating clouds and drifting islands. The train moves on its own while you flip junction switches in time to collect every star and reach the cloud station. Choose from three aerial routes of rising difficulty, unlock four distinct locomotives, track progress on an interactive route map, earn achievements, and take on a fresh daily challenge that changes every day. Built entirely in Urdu with a yellow, blue, and black visual identity inspired by an ethereal elevated railroad above the horizon.
