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!

The problem with cloust sync happens when you turn off the game. When you go back you have to sign in again. A few times I've had to start over. Inspire of this I love your apps. I have all but sudoku and variants. I seriously believe you have the best sudoku apps on all of Google Play and Ivey plates a lot sudoku. Hope this helps ty Btw, the coloring highlights feature helps a lot for people with poor vision. It makes the numbers pop and we can better see what we're doing.
