I love all the features I can use on this app. I can use a coloring feature using 9 different color options. I can feature a cell or cells to show the numbers in a different way, and I can add an X to any cell I am still working to solve to mark it another way. There is also a strategy guide that is helping me learn new techniques to improve my game. The help feature can alert me to these techniques, but I can always look them up in the settings strategy guide. This is my favorite sudoku app!

This app is exceptional. It explains the sodoku strategies so well and gives me a chance to practice them. I found Logic wiz when I was struggling to understand X-wing. At the time it was taking me around 1.5 hours to do each of the medium/hard sudoku for NYT. Since practicing with Logic wiz, I can do them, without mistakes, in under 20 minutes. It's been such a joy learning the expert level strategies. They explain it so I can, not only apply them, but also understand WHY they work.

Great app for casually playing! But I noticed while playing it would randomly pop up ads that would open my browser, like nothing would show up on the game screen and my browser would just open? Also there isn't really too big of distinction between the difficulty levels. Like I would play 'Easy' and 'Expert' and both of these levels I could solve within 2 minutes, doesn't really make sense to me.

Thank you for your review! If you encounter any problematic ads, please send us a screenshot at support@logic-wiz.com, and we'll block it. As for solving expert puzzles in 2 minutes, it is unusual since they always involve advanced strategies like XY-Wing, Swordfish, Empty Rectangle, X-Cycle and more. Could you share more details with us?
