Shadow Cubes: 3D Cube Puzzle

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.
