Read full descriptionHide full description
Three shadows: from the top, from the front and from the right. Stack cubes on the board until all three shadows match. One simple rule, many ways to think. Shadow Cubes turns the classic three-view drawing puzzle (orthographic projection) into a game you solve by turning the board in your hands. ■ How to play · Tap a cell to stack a cube, press and hold to take one off · Rotate the board to find hidden cells · Submit, and the board turns to the top, front and right views to compare each face with the target · Some cubes show up in the shadows but aren't needed. Match with the fewest cubes for a Perfect! · Start with two short tutorial puzzles to learn stacking, removing and turning ■ Shadow Tower: who climbs higher? · Mountains, Sunset, Stratosphere, Aurora… 1 floor = 1 km, up to the edge of the sky and beyond · The same puzzles for everyone. Each floor gets harder with trickier shadows, not just more cubes · See each floor's three shadows first; only the fewest cubes build a floor · No hints: climb on your own skill · See how many players are on each floor, and your rank (top %, #) · Past the sky lies space. How far can you go? ■ Chapters: one step at a time, with hints · 50 puzzles in 5 chapters: First Steps → Third Layer → Hidden Cells → Wide Board → Exactly · Every puzzle practices one case with a one-line goal, and each chapter ends with a checkpoint · Stuck? Two hints per puzzle. Collect stars on every puzzle you clear ■ Daily Puzzle · A new puzzle every day, the same for everyone. Share your stars and time ■ Your way · Four free themes (Light, Carrot, Shadow and Fairy tale), sound and vibration toggles · English, Korean and Japanese · Plays offline (except the tower's player counts and ranks) · No account, no login Shadow Cubes: a short, clean brain game for your spatial reasoning.
