    started sudoku during the COVID epidemic. bought this app . even though I am not a spring chicken and at first I struggled for a while I did persist . I wanted to be able to do the very hard puzzles without using notation just logic eventually I have learned enough logical methods to do that. I have this app for getting me started on this journey! my only regret is not trying this when I was much younger. this is a very good skill to learn for young and old alike.

    I used to play sudoku years ago and recently saw a free version with ads. The ads were a huge distraction. I downloaded this version and it's great. Even the easy ones are challenging. great way to clear your head and relax. Have fun! update: I've been playing for 6 weeks or so. Still playing easy ones but really improving my time. fun. challenging. relaxing.

    I love working on these puzzles. In the classic section of puzzles, I completed every puzzle available (6,000 + the extra 2,000 bonus). I cleared my history and have started over. I love that it has no ads in my account and allows me to work them offline as well as online. They are calisthenics for my 66 year old brain. Thank you!
