How to play

  1. Click a shape in the tray to select it — it gets a yellow highlight.
  2. Click a board cell to drop the shape with its top-left corner there.
  3. Shapes can't overlap each other or extend past the board edge.
  4. Fill all 25 cells to solve; click 'New Puzzle' to reset the board.

You have a tray of polyomino shapes and an empty board. Select a shape, then click the board cell where its top-left corner should go. Shapes cannot overlap or hang off the edge. Fill every cell to win — no gravity, just pure spatial packing.

Frequently asked questions

How do I place a shape?
Click a shape in the tray to select it (it highlights), then click the board cell where the shape's top-left corner should land.
What if a shape doesn't fit?
Nothing is placed and you'll see a hint. Pick a different cell or a different shape.
