The problem is that your weighting is wrong

Block hash ending in a-z will be heads

Block hash ending in 0-9 will be tails

It's hex.

Chance of heads (a, b, c, d, e, f) 3/8

Chance of tails (0-9) 5/8

You need to make it a fair toss. 50 50

What do you think:

Option 1: First Half vs. Second Half

This is the simplest method. You just split the 16 characters down the middle.

Heads: 0, 1, 2, 3, 4, 5, 6, 7 (the first 8 characters)

Tails: 8, 9, a, b, c, d, e, f (the last 8 characters)

Option 2: Evens vs. Odds

Another very common way to create a 50/50 split is to use parity. For the letters, you can use their number equivalents (a=10, b=11, etc.).

Heads (Even): 0, 2, 4, 6, 8, a, c, e

Tails (Odd): 1, 3, 5, 7, 9, b, d, f

Option 3: Balance Your Original Rule

If you want to keep the "letters are heads, numbers are tails" idea, you can just move two of the numbers over to the heads category to balance it.

Heads: a, b, c, d, e, f and 8, 9

Tails: 0, 1, 2, 3, 4, 5, 6, 7

Sure, that's fine

Awesome! Thanks

I like option 2 as well. Switching it now!

Tails (Odd): 1, 3, 5, 7, 9, b, d, f

If I was coding it, I would just convert to a number and mod 2, which is option 2.

Options 1 & 3 are the same.

It's probably better to go with something that is easy for the user to understand, like heads is even and trails is odd.
