Shikaku: Rectangle Logic Puzzles
Partition the grid into rectangles, each containing one clue equal to its area.
How to play
- Divide the entire grid into non-overlapping rectangles.
- Every rectangle must contain exactly one number. Its area, measured in cells, must equal that number.
- Click or touch and drag between opposite corners to draw a rectangle. Drawing over an existing rectangle replaces it.
- Click an existing rectangle to remove it. Cover every cell with valid rectangles to win.
A quick example
A clue of 6 can occupy a 1 × 6 or 2 × 3 rectangle, including rotated versions. Eliminate shapes that contain another clue.
