It takes gaming, clue cracking and mystery solving to a whole new level. Maybe it's because you have to beat the clock. This isn't just about finding a single key that gets you through a door. One puzzle leads to another and then another until you solve enough to get out. Solving each one gives you a hit of adrenaline. You're on a roll. It's the kind of thing that makes you fist punch the air. You might even let everyone know that you rule. It's all good.
