Curiosity is a multiplayer social experiment. The game setting is a featureless and minimalist white room in the middle of which floats a giant cube made of billions of smaller cubes ("cubelets") and white, floating text across each layer, usually topic related (hashtag, notifications etc.), with small messages. Players tap the cubelets to dig through the surface of each layer and reveal the next layer below. The goal is to reach the centre and to discover what is inside the cube.
And now, someone has finally made it to the centre, and has the answer to "What's inside the cube?"
