There is no official Roblox on PS5 release, but that doesn't matter as you can use the PS4 version, so here are the details for how to set it up.

Roblox is coming soon to new platforms like the PS4 and PS5, opening up its creation tools and community for many more players around the world.

Despite it not being a full-fat PS5 release, you will be able to play Roblox on PS4 or PS5 thanks to backwards compatibility on the current-gen Sony home console.

The game will be available to download on the PlayStation store on both PS4 and PS5 at this time. Roblox currently doesn't have a pre-load available and no official filesize has been given.

Roblox chat on PS5 or PS4 is not available, as the functionality is currently not supported on consoles, but this is being actively worked on.
