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.
