How the packing puzzle solver works
It tries the block with the fewest legal spots first and backtracks as soon as a block has nowhere to go. This is the same search that powers Hint in the free packing puzzle, so its solutions always match the game rules: blocks may rotate 90°, never overlap, and must sit fully inside the board.
Use it as a polyomino puzzle solver for real wooden puzzles
- Many wooden packing puzzles use rectangles plus a few blockers. Mark the blocked squares in Custom board
- If the solver says there is no solution, check that exactly 6 squares are blocked and that no region is cut off
- Want the full challenge? Play the level first and only use the solver to check your answer
