It is provably fair:

"Your lucky line will be the first three character of transaction ID and today's secret sha256 hash.
Lucky line calculate: sha256($secret:$txid)
You find here the hash keys of the secrets and here the earlier secret keys. "

And there are the secret and hashes:

http://bitbet.cc/secret.txt

or not what you meant?
