Alright, I guess I'll connect the dots for you. Although, I have to say, the site's pretty clear as far as what the hash does, and the previous round is there for you already, but whatever.

Random.org selects some numbers, encapsulates them in a string, and hashes it.
Winning numbers for next round(tiger192,4): cdec4577078b5e6f93780776bba72e9c1b4d48fc840633bc

That's the hash for next round. Write this down if you have doubts about rafflebit's sincerity.

That's the winning numbers from last round, encapsulated in a string, and released since the last round's winners already got paid out.

This is the hash of the above string from last round. If you had written the hash down somewhere, you could compare these two things to your record to verify that the numbers are genuine. We even link you to http://www.whatsmyip.org/hash_generator/ on the FAQ to endorse honesty-verification. And things like http://blockexplorer.com/address/1HeySQD9yMJLWcs7SEGCZrbtLh2Bf1dhJZ that prove payouts. And https://bitcointalk.org/index.php?topic=30515 that show proof from random members of the community endorsing the honesty of the platform.
