Christmas Sudoku from 99Games is the Japanese number puzzle game, Sudoku, wrapped in gumdrops, gingerbread and Christmas trimmings. There’s little to say about it. They changed the numbers to holiday items which I didn’t like, as it slows down recognition. But you can change it to numbers in the options.

I like the holiday time so it’s no big deal to have a themed Sudoku game. However, once the holidays are done won’t you feel a bit silly playing a Christmas themed Sudoku game...in say July? Hopefully they’ll offer an update to strip off the Christmas trim and put something else on.

The game offers about 100 levels in three difficulties - easy, medium, hard and a few other holiday themed things like creating a gift card that you can then send via email.

Christmas Sudoku does offer Bluetooth and Wi-Fi multiplayer  and looks to be a competitive format. It supports iPhone 3G, 3GS and 2nd Generation or newer iPod Touch. As I have a first generation iPhone I was unable to check into this.

Really it’s just Sudoku and you either like it or you don’t. If you’ve never played it I would suggest trying a free one online prior to spending money on an iPhone version. I’m not sure that, with all the freely available versions of Sudoku, you really need to pay for one.
