About Kaku: Shikaku Logic Puzzle
Kaku is a relaxing logic puzzle based on the classic Shikaku (rectangle division). Split the grid into rectangles so that each rectangle contains exactly one number — and that number equals its size. 2,000 handcrafted levels across 4 difficulties, daily challenges with monthly trophies, and an IQ score that grows with every puzzle you solve. Easy to learn, but Expert 13×13 boards will truly test your logic.
How to play
Drag on the board (hold the left mouse button or swipe with your finger) to draw a rectangle. Each rectangle must contain exactly one number, and the number must match the count of cells it covers. Tap a placed rectangle to remove it. Fill the entire board with no gaps or overlaps to clear the stage. Stuck? Use a hint to reveal one correct rectangle. Your IQ score grows with every clear — climb the leaderboard!
