This is a clone of a better looking sudoku app, down to having the exact same name and the same icon, but color changed. Unlike the other one, though, this one plays an ad before, DURING, and after a puzzle. It takes 45 seconds to finish an easy puzzle. You shouldn't be interrupting that. Additionally, the ads cause the game to crash frequently.

This is a generally good sudoku game, mechanics wise. There's all the features pros and beginners would need to succeed, alongside extra challenges. However, the ads are ridiculous. When you start a game, an ad will play. When you are in the middle of playing, at least 1-2 ads will play. If you use the auto complete feature, there's a 75% an ad will play. After you complete a puzzle, an ad will play. That's 4 ads in the span of one 2 minute puzzle on hard. Horrible.

Overall I like this game. I love the daily challenges and the events that pop up. I don't really bother with the star races, master games or the new zodiac things, so I just ignore those. One thing I would change though is actually making the hints give info everytime to teach something, rather than just filling in a blank cell. I don't bother using them anymore and have 115 hints saved up unused. Also, ads have increased to a laughable amount.
