Ratings and reviews

Numbers are too small. I often fat finger the wrong number and get an error. I then have to watch an ad after I do it three times. I also have to watch an ad to auto fill. Filling in initially is tedious. I like that it removes the number in the same column, row, and group when you select the final number I don't like the highlighted column, row, and square, but I could get used to that. I would give it five stars if it had only one ad per game. Love the detailed hints.

Overwhelmed with ads. If your screen times out, or if you accept a phone call, or if you respond to a text message... anything that takes the app off of the main focus of the device, you have to watch an ad. Every time you win or lose a game, or every time you switch games or change difficulty.. you have to watch an ad. I understand that ad revenue pays for app development, but there has to be a limit or something to keep ads from plaguing your time in this app.

EDIT: Seems better lately. ORIGINAL: Too many ads and ads that take control and don't release so I can go on with game. I've given it 3 chances to work better. No improvement. I watch a lot of ads, but when I'm not interested, I don't want to be forced to watch. That is just unpleasant. Great tool for teaching how to observe details but too many interruptions.
