I love a good sudoku app and overall th app is great for that but there is one thing that is more annoying than anything else the ads. If it was an ad after each game I would be fine with it but you start a game, ad, you minimize the game to go to another app, an ad, you end a game, an ad. They are completely forced and no way to skip them. It's a terrible experience overall and makes me not want to play.

Hi, sorry for such inconvenience. As a startup, we have to survive and support further development by integrating with ads. Some ads can be skipped after watching for 5 seconds. You can also purchase the "Remove Ads" service to enjoy a no-ads game. If anything else, please reach us at [email protected]. Thanks a lot. :-) - Lily

update: difficulty is better but now the ads. anytime you shut your phone down it's a 30 second long ad that's made for inadvertantly clicking on it. I just close my app and reopen so I don't have to watch them. Nice to kill time. However, doing the levels when you choose, and doing the levels when it's in a challenge, are completely different. An expert when you choose is easy and a hard in the challenges in an expert. It doesn't make sense.

Hi, thanks for your review. As a startup, we rely on ads. You can click the ">>" icon, typically appearing at the top of some Ads before and after a game, to speed up the ads. In this way, the "x" button to close the Ads will show up in around 5-10 seconds. For more info, please reach us at [email protected]. Thanks. - Lily

Nope. I wanted to like it more, but the themes/customizations were super limited (eg, I had to play several games to "unlock" the wood theme - the only attractive one - only to find that it's just a partial background, & the board itself can't be in dark mode or otherwise changed at all if using a background.) It's garish, too bright, & not adjustable. Also, there are super long ads if you want a hint! Move on if you care about appearance or avoiding ads.
