How do I solve a puzzle?
Connect the source to the receiver with one orthogonal route that does not cross itself. Collect every relay before finishing. A gate only accepts the phase shown by its color and symbol. Enter an inverter to switch between mint and amber.
Can I change my route?
Tap an earlier tile on your route to rewind to it, or use Undo. Restart clears the route so you can try another idea. Hint gives you a next step. These controls do not cost currency or require an advertisement.
What are Daily and Practice?
Daily gives you a puzzle for the current local calendar date. Practice generates more puzzles to explore. Neither mode needs an internet connection.
Where is my progress?
Progress and settings are stored on this iPhone. There is no account or cross-device sync, and the developer cannot recover deleted progress. Keep the app installed if you want to retain your local progress.
How do I change sound or haptics?
Open Settings from the home screen. Sound and haptic feedback can each be switched on or off.
