Lottery

Specifics

  • Lottery Ticket Fee for 1 ticket: 10 EBEN
  • Single User Lottery Entry Limit: No overall limit, but only 10 tickets with random numbers or 5 tickets with custom numbers can be bought at one time through the UI
  • One ticket with a 4-digit combination is generated after the payment. Each digit ranges from 1 to 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, it is almost impossible 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 EBEN 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.
