The goal is simple: divide the grid into rectangular or square sections, ensuring that each section contains exactly one numbered cell and matches its number in size. With increasing difficulty levels, Shikaku challenges your spatial reasoning and problem-solving abilities. Play at your own pace, sharpen your mind, and enjoy the satisfying logic of perfectly partitioned grids.
Shikaku, also known as Rectangles or Divide by Squares, is a fun and challenging logic puzzle game that involves dividing a grid into rectangular or square regions. Each region must contain exactly one numbered cell, and the number inside it represents the exact number of cells that should be included in that region.
Game Tips
- Start with large numbers - The bigger numbers (such as 9+ in larger grids) will have fewer placement possibilities, so solve those first.
- Use the grid lines wisely - Look at natural divisions in the grid to identify optimal rectangular placements.
- Think about constraints - If you place a rectangle incorrectly, it might leave gaps or orphaned squares that are impossible to fill.
- Ensure single-number occupancy - Double-check that no two numbers share a rectangle.
How Playing Shikaku Improves Your Brain Function
Playing Shikaku is a fantastic way to boost cognitive function and sharpen mental acuity. It challenges your problem-solving abilities and strengthens your spatial reasoning skills. As you think about how to partition the grid efficiently, you're engaging in logical thinking and pattern recognition, both of which are essential for real-world decision-making and mathematical reasoning. Additionally, solving puzzles regularly helps improve focus, memory retention, and strategic planning, making it an excellent brain-training exercise. Whether you're a student looking to enhance problem-solving abilities or an adult wanting to keep your mind sharp, Shikaku is a fun and effective way to level up your brainpower.
