Every puzzle has exactly one solution, and you can always reach it by pure logic. You will never have to guess. And no ads interrupt you while you're solving. Divide the grid into rectangles. Each number tells you the area of the rectangle it belongs to. Simple to learn, endlessly deep. — WHAT MAKES IT DIFFERENT — • No ads while you're solving. Ads appear only after you finish a puzzle, and not even every time. Your thinking is never interrupted. • No walls. No energy bars, no keys, no tokens, no level packs to buy. • Play offline. Puzzles are generated on your device — no connection needed, ever. • Verified before you see it. Every board is checked for a unique solution and for being solvable without guessing. — HOW TO PLAY — Drag from a number to draw a rectangle. The rectangle must contain exactly one number, and its area must equal that number. The board is done when every cell belongs to exactly one rectangle. — NO PRESSURE — No timers. No lives. No way to lose. Take as long as you like, and use a hint whenever you want one — there is never a penalty for it. — ACCESSIBILITY — Color is never the only way to tell things apart. Every rectangle is defined by its borders and its number, so the puzzle reads the same whether or not you distinguish colors. The palette is chosen to stay distinguishable for protanopia, deuteranopia and tritanopia — with nothing to turn on.
