About this game
Divide the grid. Match the numbers. Clear your head.
Shikaku — also known as Rectangles or Divide by Squares — is a classic Japanese logic puzzle with one elegant rule: split the grid into rectangles so that each rectangle contains exactly one number, and that number equals the area of the rectangle. Simple to learn in seconds. Quietly addictive for years.
No timers. No pressure. Just you, a grid, and the satisfying click of a board falling into place.
★ ONE RULE, ENDLESS DEPTH
Drag to draw a rectangle around a number. The area has to equal the number, and every square on the board has to end up in exactly one rectangle. That's the whole game — and it's all the game you need. Every puzzle has exactly one solution, and every solution can be reached by pure logic. No guessing, ever.
★ FOUR DIFFICULTIES, EASY TO MASTER
Start out on gentle 6×6 grids and work your way up:
• EASY — 6×6 boards. Perfect for learning the rules or unwinding.
• MEDIUM — 8×8 and 9×9 boards. The sweet spot.
• HARD — 10×10 boards that demand real planning.
• MASTER — unlocked at level 25. Sprawling 16×16 grids for players who want to be genuinely challenged.
★ TRACK YOUR PROGRESS
Earn trophy points as you solve. Build a streak. Watch your skill climb.
• Bronze medal at 10 puzzles solved
• Silver medal at 50 puzzles solved
• Gold medal at 100 puzzles solved
★ MAKE THE BOARD YOURS
Switch between beautiful board themes like Sunny, Mint Fizz and Twilight. Change the number style to suit your eye. Shikaku should look the way you want it to look.
★ STUCK? TAKE A HINT
Solve puzzles to earn coins, then spend them on a hint when a grid refuses to give in. No shame in it — the good boards are supposed to be hard.
★ PLAY ANYWHERE, ANYTIME
Shikaku works fully offline. On the train, on a plane, in a waiting room, in bed — no connection required.
★ A REAL BRAIN WORKOUT
Shikaku exercises spatial reasoning, pattern recognition, arithmetic and logical deduction all at once. If you love Sudoku, Nonograms, Nurikabe, Kakuro or other Nikoli-style puzzles, this is your next one. And if you've never touched a logic puzzle in your life, the first Easy board will teach you everything you need to know.
