But if it's the hexadecimal hash of the block, the last character won't be above f...
You're right, I clearly wasn't awake yet. I've deleted my post.
That leaves 2 possibilities:
50$ if last character of the block is a letter going from A to M (13 possibilities out of 36)
6 out of 16
75$ if the last character of the block is a letter going from N to Z (13 possibilities out of 36)
Not possible
100$ if the last character is a number. (10 possibilities out of 36)
10 out of 16
Those odds aren't bad

I'm much less good than you at math and ... it shows! If no one mind, I'll change that tiny part of the rule.
Let's say :
50$ if last character of the block is a letter going from A to C (3 possibilities out of 16)
75$ if the last character of the block is a letter going from D to F (3 possibilities out of 16)
100$ if the last character is a number. (10 possibilities out of 16)
Tell me what you think about this...
