All about the ShibaSwap Lottery!

General Lottery Details

  • Cost to enter: 1 ticket = 1 GBONE

  • Lottery Entry Limit: No overall limit, but only 50 tickets can be bought at a single time through the UI

  • When you purchase a ticket, you will receive a random 4 digit combination, each digit ranges between 1-14, for example “3-9-8-14”. This 4 digit combination is to be used to to compare to the winning numbers for your chance to win!

The Rules to Win

In order to win any of the prizes, a user must match the 4 numbers on a ticket with the winning numbers (must be in the same position, order DOES matter).

Additionally, there are prizes for matching 2 and 3 numbers in the corresponding positions!

Winning Payouts & Rollovers

  • Match all 4 numbers in the exact order = win 50% 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 10% of the pot.

  • 20% of the pot will always be burned

In the event of no winners, the match 2, 3, and 4 rewards will be rolled over as well. So in that situation 80% would rollover, and 20% would be burnt.

Let's look at an example! If the final 4 winning numbers are “3-9-8-14” then…

  • “1-2-3-4” = match 0

  • “1-9-8-4” = match 2

  • “3-2-3-14” = match 2

  • “1-9-8-14” = match 3

  • “3-9-8-14” = match all 4

Lottery Phases

The lottery will occur every 24 hours with the winning number draw occurring at 02:00 UTC! Right after the winners are selected, there is a 1 hour period where ticket purchases are unavailable.

An example of the a lottery session is below:

Phase 1 - Purchase Tickets (1 hour after the previous draw ends, between 03:00 UTC - 01:59 UTC)

  • You have 22 hours and 59 minutes to buy tickets (starting at 03:00 UTC).

  • For every 1 GBONE spent, you will receive 1 ticket.

  • Every ticket purchased is added to the lottery jackpot, which you can see in the upper right of the page!

Phase 2 - Lottery Draws (02:00 UTC)

  • The winning lottery numbers are drawn and will appear on the page.

  • Each participant’s winnings will be automatically calculated based on their ticket numbers and shown on the page.

  • If you won you can claim your winnings! Go tweet and share that you won!

  • Additionally you can see the total results of all users who matched 2, 3 and 4 numbers

  • The next lottery will start immediately after

Winning Number Draw Process

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 remainder 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 remainder of a hash encoded by the blockhash and the total pooled GBONE balance at the entry deadline.

  • The 3rd lottery number will be determined based on the %10 remainder 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 remainder of a hash encoded by the blockhash and the block difficulty at the entry deadline.
