Lottery
Specifics
Lottery Ticket Fee for 1 ticket: 20 GBEN
Single User Lottery Entry Limit: No overall limit, but only 10 tickets can be bought at one time through the UI
Paying for one ticket will give users a random 4 digit combination with each digit being between 1-14, e.g. "1-9-3-2"
How to win
To win the lottery jackpot (70% of the entire lottery pool), users need to match all 4 numbers on their ticket in the exact same order as the 4 winning numbers.
If you don’t match all 4, no need to worry. As long as you match 2 or more numbers in the correct order, you are guaranteed to win a prize.
For example, if the final 4 winning numbers are "1-9-3-2"
"2-3-9-1" = match 0
"1-9-3-2" = match all 4
"1-9-2-2" = match 3
"2-3-3-2" = match 2
"1-2-1-2" = match 2
Winning Ratio
Match all 4 numbers in the exact order = win 70% of the pot (or split the pot if more than 1 winner).
Match 3 numbers in the exact order = win or split 20% of the pot.
Match 2 numbers in the exact order = win or split 7% of the pot.
Burn the remaining 3% of the pot.
Please note - in the event that no participants were able to win a price pot on any draw, the amount allocated to winners will then be passed to the next round.

How are ticket numbers drawn
The lottery aims to be completely random. Even though the ticket numbers given out are determined by a front-end logic, there is an extremely low chance that anyone is able to determine the 4 winning numbers ahead of time.
The 1st lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the number of participating users at the entry deadline.
The 2nd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the total pooled GBEN balance at the entry deadline.
The 3rd lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the timestamp of the last lottery participant at the entry deadline.
The 4th lottery number will be determined based on the %10 remainders of a hash encoded by the blockhash and the block difficulty at the entry deadline.
