It launched at the end of June 2026 and has already passed 8 million visits, with around 3,000 players online at any time and close to 49,000 favourites.

About Build A Blue Lock Squad
Build A Blue Lock Squad is a roll-and-collect football game on Roblox, made by The LockerRoom and live since June 29, 2026. It is an unofficial fan project built around the Blue Lock anime rather than a licensed title, and its developer says so in the first line of the game description. The loop is simple: you roll for characters, more than 200 of them drawn from every arc of the series, and assemble the strongest eleven you can. Each card carries an overall rating and a position, and rare pulls of the big names such as Isagi, Nagi, Reo, Barou and Shidou are what everyone is chasing. Servers hold up to 15 players.
Progression runs on coins, daily quests and login rewards, all of which are free. Rerolls and refreshes are the currencies that gate the roll screen, and they are also what almost every code hands out. Beyond the collection there are competitive modes: 1v1 Duels, a penalties mode, a chemistry system that rewards squads built from linked players, and Cup Mode, the tournament format added in August 2026 and the one the game has featured most heavily since.
What is happening now
The experience is currently labelled FIXES on Roblox, following a run of updates through late summer that added Kunigami, Barou and Shidou content. The developer has kept a steady rhythm of one code per update or milestone, and the September codes BEE, MONSTER and SPECIALGOAL are the most generous the game has issued, with MONSTER alone worth 200k cash plus 20 rerolls and 15 refreshes. That matters because the top cards are rare, and a stack of free rerolls is the only way to chase them without spending Robux.
You have to be a member of The LockerRoom community before the code box will accept anything, and joining also unlocks a small reroll bonus in-game. The official Roblox page carries the current update label and character count.
Where new codes come from
Codes on this page come from the developer's own channels: the update label and description on the Build A Blue Lock Squad Roblox page and the The LockerRoom community, cross-checked against multiple code trackers and tested in-game. The LockerRoom does not list a public Discord or X account in its Roblox description, so we do not link to any.

Build A Blue Lock Squad codes FAQ
Why does the code box say I need to join a group?
Every Build A Blue Lock Squad code is gated behind membership of The LockerRoom, the developer's Roblox community. Join it from the group page, then rejoin the game so the server picks up your membership.
What do rerolls and refreshes actually do?
Rerolls are extra pulls on the character roll, and refreshes reset the pool you are pulling from. Rerolls are the more valuable of the two, which is why BAROUUPD, with 50 of them, is the single best code on the list.
Are TROPHIES, AWAKENED and PENALTY still working?
No. Some trackers still list them, but they date from the penalties event that Cup Mode replaced, and the sources that test codes have dropped them. They are in our expired list; if you find one that still redeems, it is a bonus.
Is Build A Blue Lock Squad an official Blue Lock game?
No. It is a fan-made project by The LockerRoom and says so in its Roblox description. The characters are inspired by the anime but the game is not licensed.
How often do new codes come out?
Roughly one per update or milestone. Character updates such as Barou, Shidou and Kunigami each shipped with a code, and the three September codes arrived within a week of each other, so check back after every update.
