Shikaku - Block Puzzle

**Shikaku — a fun logic puzzle to solve, relax, and train your brain.** Turn numbers into shapes, divide the grid into rectangles, and solve each puzzle using logic. Every number tells you the exact area of its rectangle. Draw the right shapes, fill the entire board, and leave no gaps or overlaps. The rules are easy to learn, but the puzzles get increasingly challenging. **TWO WAYS TO PLAY** • **Grid** — solve logic puzzles by dividing the board into rectangles. Each number shows how many cells its rectangle must contain. Fill the entire grid with no gaps and no overlaps. • **Stroke** — draw connected polyomino regions and shade your way across the board. A different way to challenge your brain and sharpen your logic. **PUZZLES FOR YOUR BRAIN** • Hundreds of handcrafted levels with increasing difficulty • Star ratings to challenge yourself and improve your solutions • A new daily puzzle every day • Hints and unlimited undo when you get stuck • 10+ visual themes, from pastel and minimal to neon and high contrast • Profile with avatar, statistics, achievements, and progress • Fully offline — solve puzzles anywhere, anytime • No sign-up and no permissions required **EASY TO LEARN, HARD TO MASTER** You can learn the basic rules in minutes. Start with simple puzzles, then work your way toward increasingly tricky brain challenges that require careful planning and logical thinking. Whether you want to **train your brain**, solve a quick puzzle during your commute, or simply **relax** with a satisfying logic game, there’s always another grid to complete. Play offline on the subway, during a flight, at home, or anywhere without an internet connection.
