Summary: PQ2 is definetly a great improvement for the series. The puzzles are fun, intriguing and the presentation may be simple, but quite clean and effective. It's great that you can play user-created puzzles, create your own and check your score with people around the world.
Summary: This game is VERY challenging. It makes you use brain cells, you didn't even know you had. It can be a bit tricky, and the grade scale for the games is REALLY tough. But if you play the game without worrying about the grading scale, it's really fun in a brain busting, challenging sort of way.
Summary: PQ2 is a great logical game for those who like puzzles. 1. Perfect idea. 2. Great design. 3. Very nice soundtrack. 4. Interactivity: you can apply your score to the Web, create your puzzles, download users' puzzles. This game is a challenge for your brain. The masterpiece of GameDev.
Summary: Not good on graphics. Puzzles are ok not much on the think tank if you know what I mean. Great game if you want something to do on your work breaks if you need something to stay busy but don't want to be thinking about an RPG all day.
Summary: I received this for Christmas. It has a nice clean look to it and the challenges are interesting and varied. I am sure this will be good mental exercise - after I finished playing, I found myself pondering over one of the puzzles thinking of an alternate solution. Good mind candy !!
Summary: This is an interesting game and I bet it would be great for someone that likes to memorize stuff. I'm not one of those people and I think my head is going to burst from all the memory games! So, remember this review (if you can!) when your head is about to burst from all the memorization. Yiks!
