iLounge: Every Sudoku for the iPhone Reviewed

iLounge has a nice compendium of Sudoku reviews, if you're into that. I've been reluctant to buy a Sudoku game until I saw one that at least meets the standard set by Nintendo's Brain Age game for the DS.

Update: The lone app that got an A from iLounge - Platinum Sudoku, is a winner. Very close in quality to Sudoku in Brain Age for the Nintendo DS.
