PQ (the first version of this same game, from the same publisher/maker) was already a great game, but this one definitely explores new well found ways, like the online ranking system and the puzzle making/sharing along with new moves, blocks and foes.

This is the great mind puzzle game and plus it measures your PIQ!
What's PIQ? It stands for Practical IQ.
Their catch phrase makes it fit the context: "First there was IQ, then EQ and now PIQ!"

The PIQ test is somewhat long (100 puzzles with 5 hours to do them all) but you can loosely do it with time, with the game saving your profile automatically, of course.
Then you have the weekly tests based, I think, on user submited online puzzles.
You can even, if online, watch PIQ Rankings per Country, Age, Sex, even Blood Type (how weird is that, to discover that AB is above average?)!
