This is Curiosity, a free iOS game from British gaming icon Peter Molyneux. The idea is that all of us – everyone playing the game – work together to peel off layers of cubelets that make up the larger revolving cube. At the center, a surprise (and a prize) awaits the person lucky enough, and determined enough, to tap on it at the end.
Only two people in the whole world know what’s at the center. Do you care what it is? Do you care enough to spend hours tapping on your iDevice to find out? No, really: hours.
