Blacksail Parlays

Parlay Overview

A parlay is a type of contest where participants purchase tickets for a chance to win a prize. In the context of Blacksail Parlays, users can either

1. purchase blocks for a chance to win a whitelisted NFT sent directly to the winning wallet address OR

2. users can create their own parlay game with any whitelisted NFT collection on Sonic, specifying the NFT ID, total game price, and duration; to earn Sonic.

Creating a Parlay on Sonic

1. Whitelisted NFT Collection: You can create a parlay using any NFT collection that has been whitelisted on Sonic. This ensures that only verified and approved NFTs are used in the parlay. Note: If you would like to use an NFT from a collection that has not been whitelisted, reach out to the Blacksail team for a whitelist request via Discord or TG.

2. NFT ID: Each NFT in the collection has a unique identification number, known as the NFT ID. This ID is used to specify which NFT is being included in the parlay.

3. Game Price and Duration: The game price is the cost associated with participating in the game, and the duration is the length of time the game will run. Options include anywhere from 12 hours to 14 days.

4. Block Price Setting: The block price is set based on the game price. This means that the price for each block/ticket of the parlay is determined by the overall game price divided by the number of players.

Example Game

Let's say you want to create a parlay with the following details:

• NFT Collection: Derps

• NFT ID: 484

• Game Price: 441 Sonic

• Duration: 7 days

In this example, the block price will be set based on the 441 Sonic game price, and the parlay will run for 7 days.
