It needs two tweaks to earn five stars:1. Please, please, PLEASE!!! Change the color scheme. It is very difficult to see the black dots on the current board - especially if you are not playing in bright light. The board needs to be a lighter color.2. Can you update your puzzle generator? Each game should have a unique solution. That is not the case now.Release 1.0 was a great start. I look forward to next update

This app is a very lazy implementation of the Masyu puzzle ruleset. It is in fact, incorrect, because valid Masyu puzzles must have only one solution. And the puzzles that this app generates have multiple solutions, and therefore are not valid Masyu puzzles at all. The “hard” puzzles are in fact trivially easy because there is lots of open space and no requirement for a single correct solution. Also there is no size adjustment. There is a big difference in Masyu between an easy puzzle and a small puzzle. That’s not the same thing. Even large puzzles can be easy.

This game is the perfect way to keep your brain moving. I do my masyu puzzles when on the subway, in between calls, or anywhere in between.

I’m mostly ok with the fact that each puzzle has multiple solutions, but when the “hard” mode just goes you a larger board and doesn’t really increase the number of white/black circles. The result is that the “hard” maps are the easiest of all and have literally thousands of solutions. It’s a joke.
