Shadow Match: 3D Logic Puzzle

Two ways to play. Carve the extra blocks away, or place every piece. Either way, the front, side and top shadows all have to match. 190 puzzles, one answer each.

Shadow Match is a deduction puzzle played on a 3D grid. You are given three shadows - front, side and top - and you have to find the one solid shape that casts all three.

TWO MODES

• Shadow Carve (128 puzzles): the grid starts full. Tap blocks to carve them away until the three shadows match, exactly the required number of blocks is left, and every block still touches another face to face.
• Shadow Build (62 puzzles): the grid starts empty. You are given a set of pieces and must place all of them. Mark the block you are holding, aim at a cell, rotate until it fits. Blocks that stick out of the shadows turn red.

EVERY PUZZLE HAS EXACTLY ONE ANSWER

Puzzles are machine generated and every one is verified to have a single solution before it ships. There is no guessing step - the three shadows, the block count and the connection rule are always enough to reason your way to the answer.
