81/100 stars!

I had to edit my review which was initially 5 stars and it all boils down to a stupid issue that would be pretty easy to change. The technique tutorials that begin each section use the weirdest cell numbering convention. An example to illustrate: If we assume that cell (2, 2) doesn't contain the number 2 than it follows that cell (8, 7) must. The problem is that the cells highlighted in the puzzle are not located at row 2, column 2; row 8, column 7; row 7 column 8; or any other cell one might logically say is designated by those coordinates. I don't know if I'm being completely dense or if there's some glitch but please fix this. I am specifically referencing the turbo fish tutorial in chapter 14.

Original review: So good. I'd pay money for a version with his support. I just sent feedback to the developer via the in-game feedback form. I really hope I get a quick response!

Better than own

Even after so many years, my iPhone has been upgraded several times, but this Sudoku game still remains a constant on my phone’s home screen. In terms of operation, color scheme, and tutorials, it stands out more than other games of its type. It’s even better than other Sudoku games developed by the same developer.

Bad Mechanics

Got this to learn advanced strategies, but it forces you to play through from the beginning with extremely simple puzzles. You have to “beat” 9 puzzles for each strategy to move on to the next strategy. Also there is a countdown timer on each puzzle that rushes you through. Not very conducive to learning when you’re just trying to beat the timer, or else you have to start the level over. Sudoku is already a game, no need to add these stupid mechanics to it, especially on a paid app.
