This is the second best Sudoku app that I've played, but you have to pay either monthly or yearly to remove the ads instead of it just being a flat one-time fee to remove the ads. $4/month or $20/year. The ads are so annoying, and if the yearly rate was cheaper or just a one-time $20, I'd pay. Right now, I'm not sure if I'll keep using this game or switch back to the one I've played for years. Thank you for your response, but having ads interrupt your audible book every few minutes is a hassle.

Dear user, we're sorry the adverts disturbed you, this is a completely free puzzle game, the commercials are very brief and allow you to take a break in between. We can contact advertisers to try to balance the amount of ads to improve the game experience, hope you understand!🌸😁

I liked being able to pencil in multiple... numbers on the Board . (quick slide bar option) That choice button was not available on other sudoku computer games I downloaded. However, I felt this medium board felt more like a hard board. I had to finalize a quadrant that could potential share numbers in all remaining spots. I had to steer the game in other quadrants by making up my own order in the top middle quadrant. I Never did that before. This felt like an advanced decision. Challenging

The best sudoku app out there by far. I've tried so many. The ads are few and far between. I forget sometimes it has ads at all. Which is important for me when playing his game because it's relaxing for my mind, and the ads ruin the fun and the relaxing vibe. Also a nice selection of options to personalize your experience are very appreciated.
