Real sudoku without the pencil!

If you want to get BETTER at sudoku, but prefer electronics to a pencil, this is the version you want. It has candidate marking, but YOU have to mark them and remove as appropriate. In other words, it’s just like playing on paper, but without the pencil shavings and eraser bits and paper tears. If you forget to change from “candidate” to “placing” mode, it’s easy to fix without messing up other things on the board. Better yet, if you have a “brain fuzz” day, you can turn on “show errors” mode & get immediate feedback when your logic is wrong. Best sudoku of the 4 I have installed, and well worth the 99 cents to remove ads!


If only the ads were not timed.

This is an easy-to-use game. It works the way I like it... being able to place several digits at a time instead of having to touch each cell first. That’s a real winner in my book. BUT, I may not be able to cope with ads that are forced to run for a minimum of 30 seconds. That’s ridiculous and only causes me to swear not to buy any of those products!

didn't have the feature I needed

I will only play sudoku if the game has a feature that fills in the notes automatically when turned on. I'm not going to go through by hand and fill them all in before I play. Not when the app should be able do that part for me. Nothing I tried produced that result for me, so I deleted this right away.
