How to play
- Goal
- Give every printed number its own rectangle of the stated area.
- How it ends
- Every number belongs to exactly one correctly sized rectangle and rectangles do not overlap; Undo and Erase allow corrections.
- Record
- Your first unassisted finish keeps your time for that chart; later plays are practice.
- Give every printed number a rectangle containing exactly that many cells.
- A rectangle must contain exactly one clue. Rectangles cannot overlap, but may touch along edges or corners.
- Other cells may remain uncovered. Gaps do not need to connect, and there is no full-grid coverage rule.
- Choose two opposite corners, or drag between them. Tap the same cell twice for a one-cell carpet. Erase removes the entire rectangle.
- Restart preserves the first clock. Reload preserves an unfinished original attempt and Undo; its resumed finish stays local. Reload starts a practice replay again.

Tips for Kapetto
- Count cells, not side length A clue of 6 could occupy a 1×6, 2×3, 3×2 or 6×1 rectangle when the grid permits.
- Respect other clues A proposed rectangle cannot contain a second printed number.
- Leave gaps alone A cell need not be covered merely because only one clue could reach it.
