Exactly the comment I was going to make. After playing one puzzle game on commutes for a few weeks, I'll find myself almost subconsciously doing the same sort of pattern matching against bricks or tiles or the windows on a high rise. Switch to another game and it becomes a different sort of pattern matching. The human brain, of course, is a trainable pattern matching engine. Puzzle games are great for giving it a workout and teaching it new classes of patterns. The more casual the game the better. Dots or 2048 or Mah Jong or whatever.
