PQ2: Practical Intelligent Quotient 2
has a few different ways to play the game, but the core gameplay is still the same.
You have a fairly strict set of rules and goals. You need to get your character from the start position to the white column of light. You can move any direction that is either on the same level as you, or one level higher or lower. You can walk up to certain blocks and pick them up, or you can push and pull other blocks around. There are blocks that react to switches and there are blocks that break when you put something on top of them or drop them from an area that is too high.
Above these rules, there are also two other types of characters: Police Officers and Detectives. If you are spotted by either of these characters, the level is reset and you have to start over (mind you, the clock doesn't reset). Police Officers have a flashlight that covers parts of the board, and if you step on a square that has his light on it, you're spotted. Detectives wander around until they come across your footprints (which trail you about five or six blocks back). Once they have your scent, it is very hard to shake them off.
There are quite a few more details that I can't really get into here, like laser or weight switches, but in the end, it's all in place to test your PQ, your Practical Intelligent Quotient. This score is meant to replace the standard IQ that we have been using for years. The argument is that while the IQ does seem to test your intelligence potential, it doesn't do a lot of good in testing how you will deal with the real world and practical problems. Since PQ2 poses puzzles in a 3D world with very set rules, it can better understand how you think and how quickly you process and understand the world.
Like the previous title, there are 100 puzzles that have varying degrees of difficulty. You can take the long test that throws you through all of the puzzles and get your score, or you can take the shorter, 10-puzzle daily tests that give you puzzles from the overall pool in a random order. And, if you are interested, you can post your information to a server through the game in order to see how you rank up.
Unfortunately, the game still isn't all that fun. I found myself attempting the daily tests, but I rarely felt as excited about them by the eighth or ninth puzzle as I did in the first and second. Consequently, there were more times that I just stopped playing the game than I care to admit.
