Great app for lazy Sudoku players like me!

I generally hate game apps for a multitude of reasons, but I LOVE this app. The thing I love best about this app is that it can fill the pencil marks for you. This is the part about Sudoku that I find most tedious, and it REALLY helps me want to commit to the logic part of the solves after the numbers are filled. I also love all the settings you can change, like turning off the clock. I absolutely hate being timed on things, but so many games out there are time-pressure-focused. Every once in a while I do something that sets the game board so I have to click on the cell and then hit the number I want, instead of just having the number selected and placing it where it belongs, and that breaks my brain because I can’t figure out how to undo that option. I end up having to shut the app down and restart to get back to my normal way of playing, but again, it’s something I’m doing by accident; just can’t figure out what it is. Anyway, I do play this game ALL THE TIME and I love it. The ads are SO non-intrusive, it’s like they aren’t even there. Great app!

The best mobile app by far. I virtually downloaded all the sudoku mobile apps in the market and deleted them one by one to keep this one. It also competes well with the fully fledged desktop programs. The only marginal improvement that can be added to this app is the possibility to position the candidates within a cell. For instance place the candidates on the corners of the cell or at the middle of the cell. The ideal would the ability to place individual candidates in a cell left center or right. This option will help determine whether the candidates placed in a cell are the only possibilities or if there are other possibilities. But all in all THE BEST MOBILE APP IN THE MARKET so far. I keep downloading news apps but none is a match. I can talk about the superiority of this app all day long: the choice of fonts, the coloring, the ability to enter one’s own puzzle etc etc.

Great for Beginners & Pros

This app teaches you sudoku also. I highly recommend the tutorials. They have taught me so much. The game is great after you get to higher levels of play also. I’ve tried many different apps and always return to this one. The ads are unobtrusive with absolutely no pop-ups. They have a lot of difficulty levels so you are not jumping straight from easy to hard. When you get stuck you can get a hint and have the app teach you the logic behind the hint. For the more difficult levels I love it that the app can fill in your pencil marks. Unless I’m on a plane I usually don’t want to spend 15-20 minutes filling those in. :) This is the best sudoku app I’ve seen!
