Build A Blue Lock Squad Trello, Discord & Group
Players search for a Trello board, a Discord server and a wiki for almost every Roblox game. This page tracks which of those really exist for Build A Blue Lock Squad and which are just search demand with nothing behind it.
✓ Official
The LockerRoom Roblox group
The developer's group, around 62,000 members. Joining is required before any code will redeem, and it is one of the three conditions for Sendou's free ten rerolls.
Community
Discord server
Roughly 3,000 members. New codes and update announcements appear here before anywhere else. Widely cited as the game's server, but verify the invite from an in-game or group link before joining — invite links get copied and faked.
Does not exist
Trello board
No official Trello board has been found for this game. Pages promising one are chasing search traffic. Update information lives in the Discord instead.
Verified means reachable from an official surface
Only links you can reach from the Roblox game page or the developer's group are marked verified. The Discord is listed as community because its invite is widely republished rather than confirmed from an official surface.
The group membership requirement is real
Codes check group membership before redeeming. If your codes keep failing and you are sure the spelling is right, this is almost always why.
No Trello, and that is worth saying plainly
Rather than leave the question open because it is a popular search, this page states that no board was found. If one appears, it will be listed here.
FAQ
Community links FAQ
Is there an official Build A Blue Lock Squad Trello?
No board has been found. The Discord server is where the developer posts update notes and codes, and the Roblox game page carries the current update name in its title.
Do I have to join the group?
To redeem codes, yes — the game checks membership first. It is also one of the three conditions for Sendou's one-time ten-reroll reward, alongside liking and favouriting the game.
Where do new codes appear first?
The Discord, usually tied to an update or a milestone such as a visit count or member target. Milestone codes tend to stop working once the next milestone is reached.
