Well guidgen.exe gives me {5D935866-978E-4c11-9B95-9839424687A4}, but I want to
have some fun with this, its been a long day.

So here is the game, hang GUID:

We have 8 rounds, Bill seeded the game above with his commit review.

XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
E8529E95D89D3519A31EF7DE5BD7F0D0D318E8C

Each time you reply (signed only please, take 2, see long day), delete one
character, I went first. Seven rounds to go.
