Strategy

Winning isn’t about speed; it’s about foresight. Begin each stage by scanning the grid for bottlenecks—those tight corridors where a wrong turn locks you out. Sketch a mental path that hits every corner before you lift your finger. As levels expand, look for symmetry; mirroring moves often reveal hidden routes. When you hit a dead end, reset quickly and try the opposite direction. The game rewards players who treat each grid as a living puzzle rather than a static maze. Progression is marked by increasing grid size and new block patterns, so the difficulty scales naturally without feeling punitive.
