SquareNumberPuzzle

Slice the grid into rectangles — each number is its area. Just drag to draw. Every board has one unique solution, so it's logic, never luck. A calm daily brain break.

Divide the grid into rectangles. Each number is the area of its rectangle. A pure logic puzzle you solve with numbers alone.

The rules are simple. Split the whole board into rectangles (squares count too). Each rectangle holds exactly one number, equal to how many cells it covers. Fill every cell — no gaps, no overlaps — and you've solved it. It's faster to feel than to read: just drag to draw.

No flashy effects, no complicated rules. Wrapped in a calm, paper-and-indigo Japanese design made for quiet focus.
