A calm, endlessly clever 3D puzzle. Rotate a shape until its dark shadow lines up with the blue target below — that's the whole game.
Basics, Architecture, Two Lights, Shadow Traps, Hidden, and the 50-level Master chapter where every mechanic combines.
One extra puzzle a day, scaled to your own progress. Build a streak and earn bonus points at milestones.
Race a growing AI opponent on shared puzzles — beat it enough times and it levels up to match you.
The first 40 levels are free. Unlock all 500 with a single one-time purchase — no ads, no subscription.
