The goal: Get as many points as you can. You can get them for your attire, for having your best buds with you and even for shopping. Solving puzzles and challenges is a must. Visiting a mine or going further than any other can help with those points, too. Even for those who prefer the slower pace, you can still earn a bunch of those coveted points. You can choose to collect them for only a few hours, for one day, after dark or even the whole weekend. The more you learn, the more you earn.
But why, you ask? Is it for the sake of knowledge, for the thrill of the hunt, to test your mind? For some, maybe, but for most it's for the prizes.
