S4BB has just released a new Sudoku game for BlackBerry. The game looks pretty good and has some nice features but I am not sure how well it will do for one simple reason. RIM has offered a free feature full version of Magmic’s Sudoku for quite awhile. This means that Sudoku Expert is competing against a free product which is quite good.
Sadly the game does not seem to have a trial but you can pick it up for $4.99 from the BerryReview store at this link.
Personally I would recommend giving the free Sudoku game a try first. You can pick it up by going to mobile.blackberry.com from your BlackBerry and clicking on games, then selecting free games, accepting the agreement and just select Sudoku.
