If I was already drawn as a winner are all my other tickets disqualified or are they still in the running for the next prize and then calculations redone if a winner's tickets are drawn again?
Assume that there are 100 users in the lottery and each of them has 10 tickets. User A owns ticket numbers from 1 to 10. User B owns ticket numbers from 11 to 20, and so on. Every week freebitco publish a list in their twitter to let all users know ticket numbers they own.
Let's say the first ticket picked is ticket number 5. The user A wins the first prize. If the second ticket number is between 1 and 10, that's discarded and calculations are done again.
You can click on "This lottery is provably fair" in "lottery" section and read the full explanation.
Just asking because, if I won 10th prize, but was drawn again for 1st prize. Do I win the bigger prize or am I disqualified for that?
The user who owns the first winning ticket wins the biggest prize, not 10th prize. According to the website, I have a 0.00604991 chance of winning. That is 100 times more AND it's a different number, which I don't understand how they got there.
Your chance is 0.006% not 0.006.I have 436 tickets on a total of 2,782,350. That gives me a 0.0001567% chance of winning, while the website says it's 0.01567%. In this case, there is only one winner, so no extra calculations to be done....
That's correct too.436/2,782,350 = 0.0001567 = 0.01567%
The 0.0001567 must be multiplied by 100 to get the percentage.
from my first experience of 10 Sat per roll now it is down to 10%
