Masyu is a beautiful logic puzzle invented in Japan by Maki Kaji. Our Masyu app has been in the iOS App Store since it opened and brings this challenging puzzle to your fingertips.

Masyu is played on a grid and has a simple goal: to draw a single non-intersecting loop through a set of circles scattered throughout the grid. Masyu is easy to learn and surprisingly addictive.

Under the TootSweet brand, we released three collections of Masyu puzzles: the beginner's Masyu Bug, the intermediate Masyu, and the challenging Monster Masyu.
