HOW TO PLAY
1. The board is filled with numbered clues.
2. Draw a rectangle by dragging across cells.
3. Each rectangle must contain exactly one clue.
4. The clue's number equals the rectangle's area (width × height).
5. Rectangles cannot overlap and together must cover every cell.
That's the whole rule set. Simple to learn, endlessly satisfying to master.
No account required. No internet needed. No ads, no interruptions.
Just you, the numbers, and a quiet moment.
