Logic Puzzles

Games with the Logic Puzzle mechanism let you utilize your left or right brain; I'm not sure I'm not a phrenologist.  You're using one of them to solve the puzzles in these games by connecting the dots, you know logically.  I never realized how stupid a person sounds writing about smart type thingies.  I digress.  If you're looking for games that engage your brain and make you feel like a million bucks once you put the pieces together, look no further.
