Shadow Stack: 3D Logic Puzzle

Shadow Stack is a 3D shadow puzzle with a simple idea and a lot to think about. Two lamps shine on your board. Each lamp throws your towers' shadows onto its own wall. Your job: place soft block towers on the grid so both shadows fill their dashed outlines at the same time.

One tower can fix the left wall and ruin the right one. Every move counts twice. That is what makes Shadow Stack a logic puzzle, not a guessing game.

How to Play
• Drag a block tower onto the grid
