Ratings and reviews

Update - I'm downgrading my rating on AI Factory Sudoku. Now ads show up before the start of each new puzzle and last for about a half a minute. That length of time is annoying, but it's not the reason for me downgrading my rating. It's a free app, so they have to have ads to generate revenue. I understand that. The reason for my downgrade is because occasionally an ad now pops up and interrupts my game while I am in the middle of it.

Finishing a game starts an ad from its maker for some of its other games. The problem is (1) it is about 30-sec long and (2) no cancel button shows up and eventually forces you to the Play Store. This drives me nuts because I don't want other games (come on guys, take a hint). Yes, it is fair an ad of some sort shows up, but allow me to skip after 5-sec, for crying out loud. Game is good but not worth this. It is antithetical to AI altogether. I am deleting it and moving to other companies.

I like that all like numbers light up when you place a number. I also appreciate being able to change the appearance of the board. Two big cons kind of ruin the game for me, though. For one, instructions for play are terrible. I had a hard time just figuring out how to play. Also, it would help a lot if--when you place a number--all like numbers in notes in adjoining rows & columns would disappear. You waste too much time removing them manually.
