The game offers a brain training mode, a daily rating/tracking feature, and a stress management mode. Each mode is chock-full of different types of puzzles that fit into primary categories such as focus, logic, math, memory and visual. Likewise, the stress mode likewise uses puzzles in these categories to help you manage stress, but I'll get to that in a moment.
I sat down with a fresh Monster Lo-Carb drink because nothing epitomizes learning and calmness quite like a huge infusion of liquid energy. Brain Challenge starts off innocently enough with a statement that I took as a challenge: "It's said that people only use 10% of their brains. What about you?" I've got to use at least 50 percent, right? And with the Monster drink, that's got to take it up to 55 or 60 percent, easily. I jumped into the initial challenge to check my supercharged brain rating."
