What Makes Sudoku HD+ Stand Out
Sudoku HD+ is the best way to solve your favorite puzzles on the iPhone or the iPad!
Thousands of sudokus!
There are thousands of sudokus available right now. So you should not run out of puzzles to solve for quite some time. And new puzzles will be added with every update!
Five difficulty levels!
Categorized in five difficulty levels there are enough puzzles for everyone from beginners to professionals who like even the diabolical sudokus!
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.
Online Leaderboards to compare yourself with others!
The Game Center integration allows you to compare yourself with others. There are distinct leaderboards for each difficulty level and a general leaderboard where all levels are included.
New Features to come!
Future updates will bring more features and game modes, so stay tuned for even more fun with Sudoku HD+!

Community Insight:
The only thing we think it needs is, to tell us when we have finished with a particular number, as in, filled in all nine spots with number two.
Overall we really enjoy this app but with the new update we have found that if we save a game while still playing and turn off the phone, when we come back to it, the data is lost. This was not the case previously.
Absolutely a great addictive game. We 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.
