About game
Japanese Puzzle: Shikaku is a logic puzzle where you divide the board into rectangles based on numbers. Each level gives you a grid with digits: draw areas so that each rectangle contains exactly one number, and the number of cells matches its value. The game is great for short, calm sessions and helps train attention and logic.
How to play
Press a cell with your mouse or finger and drag to another cell to draw a rectangle.
Simple rules:
- each rectangle must contain exactly one number;
- the rectangle area must match that number;
- rectangles must not overlap;
- the whole board must be filled.
For example, the number 6 means you need to make a rectangle of 6 cells around it. Valid shapes include 1x6, 2x3, 3x2, or 6x1, as long as they do not block other areas.
