The puzzles in Professor Brainium work, and there are a bunch of them, and normally that's most of what IGN looks for in a puzzle game. But it certainly wouldn't hurt if the game had at least tried to look and respond decently. There's no reason this should be less interactive than a physical book of sudoku puzzles. There are plenty of better puzzle game collections out there, many of which feature most of these same puzzles.
