Use code GAMER in the item shop to support us - thank you Fortnite has a feature called custom matchmaking, which was introduced some time ago. Without a custom matchmaking key, it is random who you are queued up with when you start a game of Battle Royale. Custom matchmaking is intended for streamers, content creators and competitive players. Streamers can use it to have fun with viewers, while competitive players can practice in the same game and server. In the beginning, custom matchmaking was only used for larger tournaments that were officially affiliated with EPIC Games and Fortnite. Then later, a select group of people from the support-a-creator program got access, and later more people from the support-a-creator program were accepted.
