Shikaku Puzzle is a logic-based experience that emphasizes spatial reasoning and mathematical area calculation. The game presents a grid filled with various numbers, and your task is to divide the entire space into rectangles and squares. Each shape you create must contain exactly one number. That specific number dictates the total area of the rectangle, meaning a '4' must be enclosed in a shape that covers exactly four grid cells. This simple rule creates a deep and engaging puzzle environment where every move must be calculated.

Sessions are designed for short, focused bursts of gameplay, making it an ideal choice for quick mental exercise. Because the rules are straightforward, you can jump into a puzzle and begin solving immediately. The challenge lies in the fact that there is only one correct way to divide the grid so that all numbers are satisfied and no cells are left empty. This creates a natural improvement loop where you learn to recognize patterns and eliminate impossible shapes more quickly with each attempt.

This title is a pure single-player logic game with no external distractions. There are no scoring systems, timers, or leaderboards, allowing you to focus entirely on the puzzle at hand. The clean interface and direct mechanics ensure that the difficulty comes from the logic itself rather than complex controls. Each session starts fresh, providing a clean slate for you to test your brain against the grid. It is a minimalist approach to the puzzle genre that rewards patience and precise thinking.

How to Play

To play Shikaku Puzzle, you are presented with a grid containing several numbers. Your goal is to divide the entire grid into rectangular or square sections. Each section you create must contain exactly one number. The value of that number represents the area of the rectangle, which is the total number of small squares it must cover. For example, if a section contains the number 6, you must draw a rectangle that is 1x6, 6x1, 2x3, or 3x2.

You interact with the game by clicking and dragging your mouse or using touch controls to define the boundaries of each rectangle. As you draw, you must ensure that no rectangles overlap and that every single cell on the grid is eventually included in a shape. If a cell is left empty or if a rectangle contains more than one number, the puzzle is not solved correctly. You must use logic to determine the only possible configuration that satisfies all the numbers on the board.

There is no time limit or scoring system, so you can take as much time as you need to visualize the shapes. It is often helpful to start with numbers that have limited placement options, such as those in corners or very large numbers that can only fit in a few ways. Once every cell is part of a valid rectangle containing a single number, the puzzle is complete. Each new game offers a fresh grid to solve.

Tips & Tricks

  1. Start with the largest numbers first to narrow down the possible shapes
  2. Look for numbers near the corners as they have fewer placement options
  3. Ensure every cell is part of a rectangle by the end of the puzzle
  4. Double-check that each shape contains only one number
