Cellway: Living Logic

Solve 20 handcrafted living-logic puzzles, then rewind any attempt and tap a traveler to see exactly why it moved, waited, cloned, merged, or stopped.

Cellway is a deterministic puzzle game about guiding living cells through handcrafted machines.

Place travelers in the green start zone, shape their route, and deliver every traveler to the blue exit. Each move happens in discrete generations, so timing and simultaneous movement matter as much as direction.

Build with simple tools, then discover deeper interactions:

• Turn travelers with arrows and mirrors • Shape routes with walls • Synchronize movement with delay pads • Navigate pushers, spinners, gates, switches, tar, and heavy travelers • Split paths with cloners and reunite them with mergers • Solve 20 handcrafted, solver-verified levels

Trace Mode lets you explore any attempt without changing it. Rewind generation by generation, tap a traveler, and see exactly why it moved, waited, changed direction, cloned, merged, arrived, or became blocked.

Play at your pace with Step and four speed settings. Cellway supports iPhone and iPad in portrait and landscape.
