If the hash of each game is made from a hash from reverse chain + hash of most recent block found hashed. How can I verify that you are using the correct hash from the chain and hash of the most recent block?

Here's the thread for the provably fair: https://bitcointalk.org/index.php?topic=922898.0

which (imo) does a good job of explaining how it works.

Also it does not use the hash from the most recently found bitcoin block, as that would be subject to a whole host of problems (timing issues, forks, difficult to verify, etc.). So the "client seed" is always the exact same bitcoin block (which was decided before we started the provably fair, but after we had already committed to a particular hash chain). You can treat it as a hardcoded constant, and check the "seeding event" to see how we fairly came upon it.
