TraceCairn

Build a route through a compact paper-like map by reading space, predicting linked turns, and choosing each move with care. Guide a marker from the entry to the exit while passing every gate in order. Each marker has directional edges. Tapping one rotates it and shifts a linked neighbour, so a small decision can reshape the route several spaces away. The first chapter introduces the rules with compact 4x4 maps and a limited number of turns. Learn to read open edges, avoid broken connections, and complete a route without repeating a node. Later maps introduce one-way studies and tighter planning. Every puzzle is designed for short, focused sessions. Use Undo to inspect a different idea, retry a map without losing its layout, and build a record of solved routes across the chapter. Clear feedback shows the connected trace, gates, turn count, and the exact moment a route reaches the exit. The game works offline and does not require an account, network connection, camera, microphone, or location access. It is made for players who enjoy spatial reasoning, finite-step decisions, and the satisfaction of turning a tangled layout into a clean path.
