A simple yet deep puzzle game where you divide the board into square and rectangular blocks, using the numbers as clues.

Each number on the board shows the size of the block that contains it. Use the numbers as hints to neatly partition the whole board.

This game has four difficulty levels you can choose to match your pace.

●EASY — A 3×3 board. A beginner-friendly stage that's easy to grasp even on your first play. Learn the rules and pick up the knack little by little.

●NORMAL — A 5×5 board. Recommended for players who want a nicely balanced challenge. Enjoy the fun of thinking and the satisfaction of solving.

●HARD — A 7×7 board. The difficulty rises with more moments that call for deeper thought. For players who like to take their time, it tests your observation and logic.

●MAX — A 9×9 board. A high-difficulty mode with a large board and complex layouts. Put your inspiration and concentration to full use in these truly rewarding puzzles.

Each difficulty holds 50 puzzles, for 200 in total. The rules are simple, but the more you play, the more the thinking-focused fun opens up.

Controls are intuitive and easy to grasp, with both button and touchscreen support, so you can play comfortably even in short bursts. Perfect for a quick refresh in spare moments or a daily brain workout.

A great pick for anyone after a puzzle game to really think through, or for adults who want to enjoy a brain-training game.
