Thanks, Equality 7-2521!
A couple questions on the spec.
it should distribute the winning based on how many numbers people get X of Y numbers (similar to how state lottos work)
Should there be a "powerball" number with better odds, like in the link you provided?
it should allow users to redeem tickets
it should set limits for when tickets can be redeemed
You prefer explicit redemption, rather than having it automatically send everyone their winnings?
EDIT: New question:
Should it pay out percentages of ticket sales (Jackpot is 50% of winnings, etc.), or should it have set prizes the way real Powerball apparently works (4 out of 5 plus the powerball gets you $10k)?
