$1B for the jackpot? I think that the chance that someone can win that prize would be lower than 0.0001%
Even if the winning percentage is not lower than 0.0001% and the winner won't actually win the same amount as the super jackpot prize pool because there is a commission of the prize which is 20%, the reward would be less 200m and the winner takes 800m.
The question is if someone won those numbers, how they would pay out the winner?
It would be great if the op include it in the thread on how they will reward the winner and explain it simple on how they determine the winner.
