A new update for Peter Molyneux's Curiosity app includes a tool to to re-grow its cube via the purchase of chipped-away cublets.

You can buy blocks of cublets in varying amounts for varying prices.

£0.69 will add 10,000 cublets. £4.99 adds 100,000 and £7.49 adds 500,000.

You can also remove the same numbers of cublets for the same amounts, creating what Molyneux hopes will become a "war of attrition".

"We don't know quite what will happen," Curiosity developer 22Cans explained in a new statement found within the app. "Curiosity may very well rapidly degrade to reveal its innermost secret or maybe the effects of automatically removing cubelets will be neutralised by players keen to keep Curiosity going."

Looking into the system more closely, it appears that the sum of cublets to be removed and added is applied to the next layer of the cube to be revealed.

So far, users have paid to remove 13,780,000 cublets and add another 4,680,000, for a total difference of -9.1 million cublets on the next layer.

The experiment is now 164 days old. During that time, 260 layers have been hammered off.

The new features will be deactivated two layers before the end of the cube.
