### Usage in Fury Racing: <a href="#usage-in-fury-racing" id="usage-in-fury-racing"></a>

As soon as a race starts, a request to Chainlink VRF is triggered. The callback from Chainlink VRF returns 2 random numbers (words). Those random numbers are then used to slightly adjust the player's car attributes.&#x20;

The bonus/malus can range from -5% to +5%. All car attributes will be re-calculated based on this percentage. Each percentage is unique per player, meaning that a player could end up with a +5% bonus while the other end up with -5%.
