Peter Molyneux's Curiosity now has in-app purchases for adding cubelets
"Curiosity may very well rapidly degrade to reveal its innermost secret," says developer 22 Cans.

An update for 22 Cans' block-tapping Curiosity - What's Inside The Cube has added a string of in-app purchases to allow users to add and remove chunks of cubelets.
Curious Curiosity owners can now pay to add or remove blocks of 10,000, 100,000, and 500,000 cubelets. The effect is not instantaneous, however, and will instead take place when the game heads to its next layer.
10,000 cubes will cost $0.99/£0.69, 100,000 goes for $6.99/£4.99, and 500,000 cubelets will go for £7.49/$10.99.
"We don't know quite what will happen in this war of attrition," said 22Cans in the description for the update.
At time of writing, 13.7 million cubelets will be removed automatically from the next layer of Curiosity, while almost 4.7 million will be added.
"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," said 22 Cans.
Curiosity has been running since November 2012, and since its launch 260 layers of cubelets have been chipped off.
