Hollowcube is a calm 3D puzzle. You empty a cube of colored cells by sliding each one out along its arrow. A cell can leave only if the path in front of its arrow is clear. The trick is seeing the right arrow in a crowded, translucent cube. Deliberately quiet: • No ads, no timer, no lives, no daily streaks. • Fully offline — complete in airplane mode. • You can never get stuck; every board is solvable. • Undo isn't destructive: try another path and your old attempt stays too — move between them freely. • Color-blind mode and a layer view. 20 levels free. Unlock the rest with a single one-time purchase — not a subscription, once and forever.
