With the exception of the ads, the puzzles are fantastic and challenge you in different ways, the tools like adding colours, notes, etc are great for note keeping, the ability to do classic sudokus not in the database is nice, though I'd like there to be a version of this for variants as well. Finally, the puzzles in the challenge section keep a constant stream of varied content, which is much appreciated. All in all, great game, and I hope all sudokus enjoyers can try this app!

Thank you so much for a great review and your kind words!!!, As for ads, we really dislike them and wish we didn't have to show them, however, they enable us to give the app for free. We try to minimize their appearance If there is anything we can do for you, just let us know at support@logic-wiz.com! Have a lovely weekend!

I don't pay money for games on my phone, but I ended up dropping $20 for this one and it was worth every penny. The variants in the free version are great, but the paid version is amazing! So much fun. And the no ads thing means no Temu ad that opens a website so they can drop a cookie on my phone and track my data.

Thank you so much for the wonderful 5-star review, and for buying premium. Coming from someone who does not usually pay for games, that means a great deal to us. We are very glad the variants are worth it, and we hope you enjoy the quiet of the ad-free version.

Great variety of sudokus and difficulties, completely acceptable amount of ads, with approximately one per sudoku. Update after a few years: I bought the lifetime premium version because i spend so much time on the app, i feel it is worth it. They keep updating the app with quality of life improvements, new optional interfaces, possibilities for customization, new puzzles and the like. I think i can spend a lifetime and not run out of puzzles
