## **What if there are no winners?**

If no ticket is able to match all 4 numbers, 60% of the pot will be moved to the next lottery session.

## How do I know that it's a fair lottery?

The use of Chainlink VRF provides users with automated and verifiable assurances directly on-chain that each lottery drawing is provably fair and was not tampered with by the oracle, outside entities, or the Polywhale team. Read all about our Chainlink integration [here](https://link.medium.com/UZqmkITocgb).

## **Can I swap my tickets back to KRILL?**

No, once purchased you will not be able to convert your ticket back to KRILL.

## **How will I know if I have won?**

You can manually match your ticket numbers with the winning numbers for greater excitement. If you’re too lazy to do this, we’ve calculated your winnings automatically for you on the page!

## **If I win, do I need to manually claim the prize?**

Yes, you will need to click the “Claim Prizes” button on the lottery page.

## **How often is the lottery?**

Each full lottery session will run for 6 hours.

## **Where can I see the winning ticket numbers?**

At the bottom of the page.

## **Are all ticket numbers unique?**

There are a total of 38,416 different ticket combinations. This may be adjusted later based on the number of participants.

Ticket numbers are given out randomly. As such, there is a small chance that a user receives the same 4 digits in two tickets held.

## **What if someone buys all of the number combinations?**

This is close to impossible as ticket numbers are given out randomly. One participant is able to acquire 2 tickets that have the same 4 digits, so they would have a very hard time acquiring all of the unique combinations.

## **What transaction fee will I pay for buying a ticket?**

Each ticket purchase will require a unique transaction. For example, buying 2 tickets will require participants to pay for 2 transactions. The same will apply when claiming rewards.\
