Keep doing the games! I found that after doing this, I would often notice patterns in the questions, but this is only because I have been used to doing them for so long. Also, spend more time upfront on the diagram, it may sound counter-intuitive but this is your best bet for success. If you were like me, then things will just "click" one day...you'll have that moment where everything starts coming together. Try and have habits; most logic games are either pure sequencing, grouping, or a combination of both. Determine the game type up front. I have found that simply looking at a bunch of stimulus' without writing anything down and then sorting out what the instructions are in my head while trying to do 1 or 2 questions, is great as a training exercise.

Good luck

I did remember seeing on a recent pt somewhere in the late 80's a return of the circle games (which is basically a sequence game with the first and last slots connected) and a pattern game, which is just conceptualized as a pure sequencing game. Other than that it is fairly standard for logic games
