🧠 How to Play

Each puzzle contains a grid with numbers placed inside it.

Your objective is to divide the entire grid into rectangles.

Every rectangle must follow two important rules:

1. Each rectangle must contain exactly one number.
2. The total area of the rectangle must be equal to the number inside it.

For example, a rectangle containing the number 6 must cover exactly 6 grid cells.

Think carefully, draw your rectangles, and solve the entire board.

✍️ Easy Drag Controls

Shikaku features an intuitive drag-to-draw system.

Simply select a starting position on the grid and drag to create a rectangle. If you make a mistake, tap or click a placed rectangle to remove it and try again.

The simple controls make the game easy to understand while keeping the puzzles challenging.
