Zen – Shikaku Logic Puzzle

Zen – Shikaku is a calm logic puzzle built for quiet focus. The rules are simple: divide the grid into rectangles so that each numbered cell shows the area of the rectangle it belongs to. One number, one rectangle. Every cell belongs somewhere. No timers pressuring you. No clutter on the screen. Just a warm, unhurried space to think — whether you have two minutes or twenty. How it works Draw rectangles on the grid until every cell is covered. Each number tells you how large its rectangle must be. Rectangles cannot overlap, and together they must fill the board completely. Easy to learn, satisfying to master.
