Peter Molyneux’s gaming experiment Curiosity: The Cube saw overwhelming demand from thousands of users, and 97 million “cubelets” have already been destroyed on the first layer, with the average daily destruction rate for each user at 306. Molyneux reported yesterday that 2 billion in-game coins had been spent and 625 people have purchased the 1 million coin chisel.

“I now understand what’s going on, basically we and our server are overwhelmed by the number of people trying out the experiment,” tweeted Molyneux. “Everyone please remember something as concurrent as this has never been attempted before, and we’re just a tiny company.”

Curiosity: The Cube is free and the first of a series of “experiments” for Molyneux’s 22 Cans studio. Users strip away layers of a cube by tapping, but only the user who removes the final cubelet will get to see what’s at the center of the cube by video link.
