Best Sudoku App!

I love this app. It has beautiful graphics, something other sudoku apps have found strangely difficult to master. It also has thousands of levels, unlike many other (paid) apps. I'm also in love with the noise it makes when you punch in a number or slide to a different spot. The "levels" are a great idea, and I love that you can go back and look at your stats.

Another great feature is that it only highlights something as wrong when it's contradicted by something else on the board, instead of highlighting it when it simply is wrong. It allows you to make mistakes, and you don't end up accidentally cheating, as you do in other sudoku apps. In addition, it has little or no glitches, and has never crashed on me. While it does have ads, which other users are upset about, it only has a small ad bar on the home page that doesn't get in the way, and you rarely see it. This is by far my favorite sudoku app.

Could use a checking thing

It just needs a way to check the answers. When I get stuck, I guess, and I don't want to get to the end of the game just to find that my guess was wrong and have to go back to where I guessed. Needs a way to check the answers in the game.

Also, when I try to input a number (this is on quick mode, btw) it deletes the memo number instead of writing in the number. At one point, I had to press the number five times before it put it in.

Other than those things, fantastic app. It's fun and challenging, and more rewarding than other sudoku apps.

Sudoku Brilliance

This is without a doubt the best Sudoku game out there for iOS.

It's cleverly designed. Filled with beautiful, intuitive interfaces and obscure, yet cute, icons. It has a very wide range of difficulty levels, that in my experience have been very consistent in how difficult they are.

The achievements, scores and statistics, along with a great daily puzzle feature are all integrated perfectly. These extra features also help to give the game a social, competitive edge that no other Sudoku apps can even compare to.

I will say however, after having played a different Sudoku app for quite some time. I had gotten extremely used to the UI for solving the puzzles. It took quite a while before I adjusted to the clever UI of MoonRabbit's Sudoku. Too be frank, I think I'm still a little faster with the other app.

All in all, this is a fantastic game. Well designed, well written, well played.
