4 stars: Excellent implementation. Very easy to operate. Suggestion: Please can you add more puzzles?
5 stars: Various levels of difficulty are the best part of the game.
3 stars: Plenty of games, proper difficulty leves. I love the classic keyboard layout and chose it because all other Sudoku apps have a 2 line-layout with is very unintuitive. 2 things keeping it from more stars though: 1 is that Dark Mode only cover a couple of windows, but not all or even most. 2 is that the keyboard is unecessarily small, there is lots of space for it to expand without covering the ad banners in the bottom.
4 stars: I liked it only problem is once you do all the puzzles in each group you have to reset each one individually. So the completed ones stay filled in where they should just rotate back into list of games. It's not like you are repeating games you may already know. No one can remember a previous puzzle.
5 stars: I enjoy the game. The number highlighting feature when filling a specific number makes thinking and reasoning easier.
4 stars: Very challenging. Has variety and appropriate levels of difficulties for different abilities. Very satisfied. However, please take off the pencil icon. Revert back to the previous method of making notes.
3 stars: I like the different game types it has. It reminds me of my old game \
4 stars: 3rd row of buttons is a few pixels to the left relative to the first two rows in \
4 stars: I knew nothing about Sudoku before!...
