About this 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

WHY PATCHES STANDS OUT FROM OTHER SHIKAKU APPS

REAL-TIME BATTLE ARENA
Most Shikaku and rectangle puzzle apps are solo-only. Patches lets you race real players live on identical boards, or practice against adaptive bots that solve at human speed.

WEEKLY & MONTHLY TOURNAMENTS
Compete on global leaderboards for trophies and in-game rewards, not just a personal streak.

1,500+ HANDCRAFTED LEVELS
From gentle 5x5 grids to brutal 8x8 layouts. Every level is hand-checked for a single logical solution.

DAILY CHALLENGES
Fresh puzzle every day. Build your streak and compare with players worldwide.

OFFLINE PLAY
Solve grids anywhere — flights, commutes, no connection needed.

CUSTOM THEMES
Dark mode, color palettes, and board styles to make it yours.

WHO IT'S FOR
- Fans of Shikaku, rectangle puzzles, grid puzzles, and area logic games
- Sudoku, nonogram, and picross players looking for a new daily habit
- Anyone who wants real competition, not just a solo streak
- Commuters who want a calm, satisfying mental workout

Sharpen your spatial reasoning, division, and geometry instincts — one grid at a time.
