Shikaku Puzzle
Slice a numbered grid into rectangles that match every clue exactly.
Developer: Playgama
Play Shikaku Puzzle Online for Free
Shikaku Puzzle is the classic Japanese logic format - divide a grid into rectangles so each one contains exactly the number written inside it, no more, no fewer. It's a quiet, deduction-heavy shikaku puzzle with almost no learning curve but real depth once the grids grow past a handful of numbers. Good daily brain-training pick for people who like Sudoku-adjacent logic without the sudoku saturation.
How to play
Draw rectangles on the grid so each rectangle contains exactly one number, and that number matches the rectangle's total area.
Controls
Mouse drag or touch drag to draw rectangles.
