Five difficulty levels!

Two different modes to enter your solutions!

The Dual Pad Mode gives you two distinct keypads, one for entries and one for notes. The alternative is a Single Pad where you can switch between entering entries and notes and have bigger buttons. You can switch between the two modes at any time in the options menu!

Save & restore!

If you need to try out a solution, but you are not shure if it is correct, you can save the current state and come back to it whenever you want!

Support through Smart Notes!

If you enable Smart Notes the app will fill out all the possible notes and remove those which get impossible by the solutions you enter. This may give you just the bit help you need to solve those really hard puzzles!

Multiple levels of error checking!

With three levels of error checking there is a mode that suits everyone. The default mode will show you if you enter a number that is not possible at the field at the current time. Additional you can enable this error checking for the notes. The last option will show you if a number is wrong immediatly when you enter it.
For those who don't want any help all options can be disabled.

Not as hard as I thought it would be

The only thing I think it needs is, to tell me when I have finished with a particular number, as in, filled in all nine spots with number two.

The new update is not great

Overall I really enjoy this app but with the new update I have found that if I save a game while still playing and turn off the phone, when I come back to it, the data is lost. This was not the case previously.

Sudoku HD+

Absolutely a great addictive game. I have tried many sudoku games and this is by far the best! Four levels of difficulty, hundreds of games in each level. And it's FREE!!!!!!!
