## What is shikaku?

Shikaku is a relaxing yet challenging Japanese logic puzzle. The rules are simple, but mastering them is the real fun.

HOW TO PLAY
Divide the entire grid into rectangles. Each rectangle must contain exactly one number, and the area of the rectangle must equal that number. Fill the whole board with no gaps or overlaps to solve the puzzle.

Just drag to draw a rectangle, tap to erase. Easy to learn — hard to master.

FEATURES
• 100 handcrafted levels, each with a guaranteed unique solution
• Difficulty that grows steadily — from gentle 5×5 grids to expert 16×16 boards
• Earn 1 to 3 stars on every level based on your speed
• Daily streaks, achievements and detailed stats to track your progress
• 4 beautiful color themes
• Helpful hints whenever you get stuck
• Resume any level right where you left off
• Pinch to zoom and pan on larger grids
• Satisfying sounds and haptic feedback
• Play completely offline — no ads, no internet required

Whether you want a quick brain warm-up or a deep logical challenge, Shikaku gives you a clean, modern puzzle experience. Perfect for fans of Sudoku, Nonograms and other Nikoli-style logic games.

Train your brain. One rectangle at a time.
