What are the Odds of Getting Even?

Even as a small boy, Heinz was a maths genius, which explains why everyone calls him Number One Heinz. But as well as numbers, Heinz also loves playing tricks on people. This other passion lays the foundation for his future career: Heinz becomes a crook.

How does Zero Joe manage to crack the code of his prison cell? When is payday? And how do the crooks divide the booty up between them?
