Great features in that you can turn off/on error checking, note taking, etc. No ads is wonderful! The only reason I didn't give 5 stars is that I had to reinstall it (no fault of the app) and it lost the ability to filter the games by whether they were completed or not, and lost the ability to populate a blank grid with a custom puzzle. I really miss both of those features.

Ad Free. Claims you can add more puzzles, but that functionality either doesn't work or is unexplained and unintuitive. Website for support is dead, which means you can't read up on how to do it. Really needs a way to generate new puzzles on the fly, and needs to make it easier to add the new puzzles. Menu IS there in Android 10, just smushed to only one line (but you can scroll it). If I could add more puzzles, this would be a 4.6 star.

With most sudoku apps, it will tell you if you've placed a number incorrectly. This one only checks to see if that number already appears in the same row or block. I thought I found an unsolvable puzzle once, but I later realized that it hadn't told me that one of my numbers was incorrect. The UI is aesthetically unpleasing but functional. Otherwise, the app is fine. I do appreciate that it's completely ad free.
