Why the past? The current game should get it from a future date, so no one (not even the house) knows who will win until the draw. Otherwise, someone will game your game... you know, and win all the time.
In fact, when I said "past", I meant the "other two modes" of string generator available at random.org as explained here:
http://www.random.org/faq/#Q2.6You used one mode at you lotto ("Using pregenerated randomization from date") and that's what I am using here right now.
As they mention:
The other two modes allow you to select a pregenerated randomization, which means that your numbers or strings will be based on randomness generated by RANDOM.ORG some time in the past. These modes allows you to replay a given sequence of numbers at a later stage, and allows multiple parties in different locations to get the same numbers in a predictable fashion. These modes effectively turn RANDOM.ORG into a pseudo-random number generator.
P.s.: I'm thinking about using the third mode ("Using pregenerated randomization based on persistent identifier"). Maybe the identifier might be my secret for each round...
A better approach (for multiple draws per day) might be replacing the string from random.org by the following/next secret revealed at
"Little Bit at a Time" after the tenth (last before draw) ticket bought (and confirmed) here.
I guess I'll go for that way in order to maintain a good scenario of Provably Fairness...
What do you think about it?
Note: Gentlemen, I'll release 2nd round in a few hours after thinking a bit more about this "random stuff" and Provably Fair dilemma.
Thanks in advance for comprehending.
