100 hand-crafted logic puzzles where every arrow has a path. Tap them in the right order to clear the board.
No timers, no energy bars, no friend-spam. Just clean puzzles that get smarter, one level at a time.
From gentle warm-ups to brain-melting 50×50 boards. Each puzzle is verified solvable by the same solver that powers your hints.
Stuck? The bulb runs a full solvability search and points only at safe moves — never at a tap that fails or dead-ends the board.
Warm cream by day, cocoa brown by night. One tap in Settings.
Every level is bundled with the app. No connection needed once installed — perfect for flights and commutes.
No push notifications nagging you to come back. The game waits for you, not the other way around.
Dense puzzles fit the screen, and you can pinch in to focus on one corner at a time. Double-tap to reset the view.
Each arrow points one direction. Tap it and it slides that way until it leaves the board.
If another arrow is in the way, your move fails and you lose a life. Order matters.
When every arrow has exited, the level is complete. Move on, or go back and try with fewer lives lost.
