Polyomino
Every piece has its place — find it
Polyomino is a spatial-reasoning puzzle of fitting irregular tile shapes into a grid with no gaps and no overlaps — think Tetris pieces as a calm, deliberate puzzle rather than a race against the clock.
How to play
- Drag every polyomino piece from the tray onto the board.
- Rotate (R) and flip (F) pieces so they fit together.
- Fill the board completely — no overlaps, no empty cells.
- Stuck? A hint places the next piece, at a cost to your score.
