Ratings and reviews

This is the PERFECT sudoku app! I initially downloaded it because it was free, had no ads, and didn't need suspicious permissions. (In the play store it says it needs wifi access, but once you download the app it never asks to use the wifi) I love the game interface as well. Yes, you have to press the number you want to enter first, then press the empty square. It literally took me two tries before I trained myself to do this. Some reviewers seem to be flummoxed by this stunnigly complicated mechanic. I am addicted to the mechanic whereby when you enter a number in pen, it highlights the number in yellow if it currently works in that position. BUT!!! A number in yellow doesn't necessarily mean that it is correct, just that with other numbers currently on the board it works. I think some who have claimed to find bugged puzzles may have run into this confusion. I love that you can enter possible numbers "in pencil" just like some of us do on a paper puzzle.

A lot of potential here, but ultimately buggy and even broken at times. This would be 5 stars easily without the bugs. As of now many games have to be abandoned due to glitches, and it's lacking a bit on basic features (line pressing back after solving to exit, rather than continuing the time on a solved game).

I used to hate Sudoku puzzles, but this app has really made a difference. Having the option to put temp marks is super useful, and highlighting which number you're on makes it so easy to keep track of what you're doing. The graphics and design are simple, but clean and easy to navigate/use
