Patches: Shikaku Puzzle Game

Divide the grid into perfect rectangles. Match every clue. Leave no gaps.

Patches is a Shikaku puzzle game — the classic Japanese logic puzzle where you split a grid into rectangles and squares, and each shape's area must exactly match the numbered clue inside it. Simple rule, deep strategy, and every one of our 1,500+ levels has exactly one correct solution — no guessing required.

HOW TO PLAY
- Tap a numbered clue cell
- Draw a rectangle or square around it
- The rectangle's area must exactly equal the number
- No overlaps — fill the entire grid to solve the puzzle
