I loved the game. The varients were interesting and fun but after playing for a while I started getting ads in the middle of game play. Almost to point where it's after every input (granted I was playing on expert and sometimes had a long time between inputs). Unfortunately I have to uninstall because I absolutely hate games that interrupt game play for ads.

edit: the game is so good, lots of free variants, the hints make sense if you need them. they're very satisfying to play. the ads are intrusive, but no more so than other free apps of this type. I don't mind spending 10 seconds waiting, it gives me a chance to look away from my phone and rest my eyes. if you get a sketchy ad, just submit a ticket through the support/feedback button. They technically don't control the ads so if there's a bad one, just report it. I did that and Udi was awesome

An excellent soduku game, maybe the best one i've tried, but $23 to get rid of ads and unlock the other variations is kind of insane. It's got enough ads to make me really want to pay to turn them off but not that much. If it was priced similar to their Sugaru game (which is also excellent) I would definitely buy it, but $23 is a bit aggressive for me when there are dozens of Soduku games that are very good.
