Zyl is a puzzle built around elegant path tracing. It's a small, quiet game. Soft colors, clean lines, and nothing on screen you don't need. Drop arrows on the grid to guide each path from its start tile to an exit. Pick up the stars on the way. When you're ready, hit Play and watch the route run. The rules: • Drag arrows onto the grid. • Send every path to an exit. • Pick up every star. • Hit Play to test the route. • Reset and try a new approach whenever. It starts simple, but then the difficulty ramps up: • Boards don't always use a clean grid. • Some levels have more than one start, or more than one exit. • Split arrows send a path off in two directions at once. • Merge arrows converge two paths into one. • U-turn arrows re-route a path from where it came. A few things worth knowing: • 300 handcrafted levels, each built around a single idea. • Levels stay small. Most of them can be finished in less than a minute. • Cloud save syncs your progress across devices. • Relaxing music and sound design. • No timers. • No ads. • No in-app purchases. • No data collected. Every puzzle has a solution. Some have multiple. The fun is in finding it.
