Many new adventures are available to players of LEGO Fortnite on LEGO Islands: new custom experiences made in the Unreal Editor for Fortnite. UEFN allows players to create their own custom game modes in Fortnite, and LEGO have used it to create their own custom experiences. LEGO Obby Fun features challenging obstacle courses while LEGO Raft Survival challenges players to set sail, build rafts, and survive an onslaught of pirates on the high seas.
LEGO Fortnite Islands are different from the standard LEGO Fortnite game mode, so they could be a nice change of pace if you’re busy building LEGO Rocket Ships and flying hot air balloons. There are two main ways to play these new LEGO Islands: searching for them via Fortnite’s Discovery tab and using Island Codes.

LEGO Fortnite: How to Build (& Fly) A Balloon Platform
Balloon Platforms are perfect for traveling vast distances in LEGO Fortnite. However, they can be hard to build and require lots of resources.
How To Play LEGO Fortnite Islands Using The Discovery Tab
To open Fortnite’s Discovery tab, simply click the search icon at the top left of your lobby screen. This opens a search page where you can browse all of the custom experiences created by other players. The search page has options, allowing you to search for specific game modes, such as prop hunts, roleplaying experiences, and racing games. Unfortunately, LEGO doesn’t have its own category, so you’ll have to just input “LEGO” in the search bar.
Your search should return a few dozen LEGO-based Fortnite experiences, some made by other players and others made by Fortnite and LEGO’s own developers. This includes Obby Fun and Raft Survival as mentioned above. Just select the game mode you want to play, and Fortnite will place you back in the main lobby where you can choose whether you want a public or private game session.
As these game modes are based on LEGO Fortnite, any character Outfits such as those included in the latest Fortnite Crew Pack will appear in LEGO minifigure form if they have one.
From here, just click Play and you can jump into any LEGO Fortnite Islands, either on your own or with friends. If you prefer, you can also scroll down on the Play tab to find modes, but it can be a bit difficult to sort through all the modes listed.
How To Play LEGO Fortnite Islands Using Island Codes
All custom experiences in Fortnite have their own Island Codes: a short sequence of numbers that you can use to find them immediately. These are particularly good if you want to share relatively unknown game modes with friends. To use them, just enter the Island Codes into the search bar. For example, LEGO Obby Fun and Raft Survival both have Island Codes:
- LEGO Obby Fun (6344-4048-9837)
- LEGO Raft Survival (2975-0725-2749)
Making custom experiences using UEFN has changed the game significantly, with creators using the editor to update traditional classics with a Fortnite twist. Players should keep an eye out for new LEGO Fortnite Islands as creators get their hands on these new tools.
