Welcome to the SwapFish lottery, the first of its kind to be offered on the Arbitrum chain.
Participate in the lottery for a chance to win huge FISH prizes! It’s extremely simple, fun, and you can participate as many times as you like, as long as you have enough FISH to buy the tickets.

Rules of the game

  • Price of 1 ticket = 5 FISH;
  • Individual user entry limit: No overall limit, but only 100 tickets can be bought at a time;
  • Each ticket will give users a random 6-digit combination with each digit being between 0 and 9, e.g. “1-2-3-4-5-6”. In order to win prizes, your numbers should match the winning ticket from left to right - the more numbers that match, the bigger the prize;
  • To ensure fairness, the lottery uses Chainlink's implementation of VRF for true, secure randomness.

How to win

Match numbers from the left side of your ticket to the winning numbers drawn at the end of a lottery round.
  • Matching even just the first number will win you a small prize.
  • Match more numbers to win a share of a larger prize pool.

‌Prize eligibility

‌There are a total of six numbers on each ticket. To win, your numbers need to match the drawn numbers in the same order, starting from the left of the ticket.
You will only win prizes from the highest prize bracket you are eligible for. A ticket matching the first three numbers will only be eligible for prizes from the “Match first 3” bracket, and not for the “Match first 1” or “Match first 2” brackets.
Remember: The digits must match in order, starting from left to right.

Prize sharing across prize brackets

‌After a round is drawn and tickets with matching numbers are determined, the prizes are awarded. The amount won by each ticket will depend on how the amount of FISH in the prize pool and on how many other tickets won in the same prize bracket.
‌For example, if you have the only ticket that matches three numbers in order, and the predetermined share of the prize pool for your bracket was 10.000 FISH, you'll receive the full 10.000 FISH.
If, however, 5 tickets match the first three winning numbers, each ticket holder will receive 2000 FISH in prizes.

Buying multiple tickets at once gives you a bulk discount on your purchase. You can buy as many as 100 tickets in one purchase, with the discount starting small at 2 tickets, and scaling up to 4.95% at 100 tickets.
