Really nice app, i love that the ads are banner style so it doesnt interrupt your game at all. My only criticism is that i wish there were harder puzzles available. The "expert" level (hardest puzzles) have 3 or 4 given numbers per 9-square block at the start of the game, so you start with about 1/3 of the numbers already filled in. Would love to have a harder game. Thanks!

I've used this app for years. Lately the ads have become increasingly distracting and malicious, with no way to report or close the suspect ads. The current ad blasts a red flag continuously, and if you try to cancel the banner, then it basically routes you to a sketchy Chinese site that is indecipherable. I have to keep closing the app because it will not go away. I guess it's time to find a new app and delete what has become a malicious app. Fun while it lasted. Now garbage. Update: garbage

We take the quality of advertisements that go into out apps very seriously. The behavior you are describing is certainly not intended nor allowed. Would you be willing to work with us on identifying the offending ads and correcting this problem? If so, please email us to debug@genina.com. Update: still waiting to hear from you via email.

Generally good. Would be nice if more distinction between initial cells and my entries. Bold/not isn't much different on my screen. Only other option is TOO different. Bug on my android, which has tiny menu bar along upper right edge of screen: touching it while tapping digit into one of the cells it partly covers (col 9, rows 1,2,3) puts digit into row 1 col 7. Would like to see the full process of hint logic. Usually a few pencil steps I can follow, a pause, then a number, not always clear why
