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.
Features
◇ Intuitive to play
Drag to draw a rectangle, tap to remove it, redo as often as you like.
◇ Four difficulties

◇ A daily puzzle
One shared board for everyone each day, with a streak counter and calendar.
◇ Every puzzle has one unique solution
Each board is verified by a solver to be uniquely solvable — so it's always
logic, never guessing, right to the last cell.
◇ A gentle hint
Stuck? Reveal one correct rectangle and keep your momentum.
◇ Your stats
Best and average times per difficulty, no-hint rate, total time, and a daily
calendar — quiet progress you can watch add up.
