How to Play

Fill the grid with rectangles by dragging from one cell to another.

1. Each rectangle must contain exactly one clue number.
2. The rectangle area must equal that clue value.
3. Rectangles cannot overlap and must cover the entire board.

Click Press here to begin on the board overlay to start. Use right-click or the Erase toggle to remove rectangles.

Rule-invalid rectangles can still be placed while you work; they are shown with a thick red border until corrected.

Cells with clue value 1 are auto-filled on fresh puzzle load and restart.

Undo, Redo, Pause, Clear All, and Restart are available during a puzzle. Your progress and best times are saved locally in your browser.
