Sudoku 2 was the top app that kept coming up when searching for a sudoku app so naturally I had to check it out.
Sudoku 2 took the classic sudoku game and added some things on top of it.
It has all the basic features pretty much any sudoku app has, like adding notes, a game timer, different levels, and personal stats.
On top of that they added:
- Auto-select of all numbers - when you touch the number 2 for example it shows you all the other 2s you already have on the board, makes it easier to see what the situation is
- Highlight notes - when you touch a number on the board it also highlights any place where you have that number written down as a note. Very useful
- Auto-remove notes - when you discover what number goes in a specific spot the app removes it from all the notes it appears in. This one could be considered a bit of cheating but you can turn it off, like all the other features here.
- It looks good and you can choose from several different looks
- OpenFeint integration - you can rank and compare scores and achievements with your friends or anybody else playing the game
There is also a pro version of Sudoku 2 but I don't really know what the difference is between the two (maybe just no ads).
Just get the free one.
