Great game, completed the hardest 500, please add more. Comments about ads... shutttt up! There really aren't that many at all, they aren't annoying or intrusive. Game designer have to make some money. Apart from more games/levels in the 2 hardest groups please keep it exactly the same.
Used to be great. Too many ads with sound you cannot silence. I'm completely fine with ads for a free app; they have to make money. Just the ones with videos/sound make using this intrusive in certain environments. At least allow a silence mode. Also, sometimes the blank add popup blocks the pencil function. Every time you select the pencil, you launch an ad.
*UPDATE- SOMETHING KEEPS CRASHING IT EVERY FEW SECONDS! Omg. It says odd can't open, and occasionally without my help it opens an ad in a browser. It's my favorite and now I can barely play it. It goes to resume screen each time. This only started last week or so. Please fix to get your stars back! I really don't want to find a new one when this one helped me learn to play and I'm only halfway through medium! 5* A GREAT Sudoku game with many many levels and puzzles. I had just learned to do 5his puzzle from a friend after years of failed attempts, but the beginner levels were so helpful that I finally got it and now it's my favorite puzzle game! I like word searches and jigsaws, but this is great. The ads annoyed me at first, but now I love it so much I don't mind them at all! I would recommend this Sudoku game to anyone interested at any level of expertise. Thanks guys! :)
This was a very good game app. But now the ads are so bad that it makes the game unplayable. This sudoku game is challenging yet makes doing the puzzles easy. I have mixed feelings about the way it will not let you put the wrong number in a square. I like the way it keeps track of any mistakes you make. This does help in solving the problems quickly without trying to find your mistakes.
I just switched over to Android, and the Sudoku game I used on iTunes was not available, I have tried several free games, and this was by far the best. The only reasons for no fifth star: 1 expert is not hard enough, and 2 I like some sort of scoring system other than just a clock... Used to have 4 stars. Now 2 stars because of the ads that interrupt play. I don't mind ads at the beginning, or end but during the game really sucks, if you are in pencil mode, it defaults back to pen after the ad. Down to 1 star, haven't played in a while because of the other issues, but recently tried. The ads now block the pen/pencil so you can't switch modes. After lowering to 1 star was contacted and they said they would address the issues, I haven't used the game in a couple of months, when I tried it today the advertisement issues seem to be gone. Back up to 4 stars, glad to see they listen to feedback!
Would give a 5 star rating. Played all the time HOWEVER now it almost impossible to play. Game keeps going to browser to try other games.
General bug fixes and optimization which brings you better gaming experience!
