Blue Lock Card Battles Codes (Active and Expired)
Last checked July 6, 2026 (UTC)
Blue Lock Card Battles hands out Cash by the million with every patch, and the ELO plus NEL event brought a fresh wave. I verified this list against Pro Game Guides and Try Hard Guides today, and SORRYFORDELAY10 is the headline at ten million Cash.
Blue Lock Card Battles codes are the update and apology strings the Blue Lock Card Battle team pushes out with each patch, event, and delayed release, and every one of them pays straight into your Cash balance for free Cash, in multi-million chunks. Cash is the only thing that matters in Blue Lock Card Battles. It buys the card packs you pull your strikers from, expands your team roster, and raises your income rate so the next pack comes faster. A single code wave like the current one stacks over twenty million Cash, which is several packs of pulls you did not have to grind matches for.
Quick tip. join the official Roblox group and like the game before you touch the code box, because redemption checks for both and fails silently otherwise. Then redeem all five in one sitting and open packs during an event banner, that is where the pull value peaks.
New Blue Lock Card Battles codes track the patch cycle, CARDUPDATE21 shipped with card update twenty-one and the next patch will bring a CARDUPDATE22. The team also has a habit of apology codes, and those are the fat ones, SORRYFORDELAY10 paid ten million Cash for a late update. Redemption is the cog icon in the bottom right, but only after you have joined the Blue Lock Card Battle Roblox group and liked the game. One use per account, and update codes retire as newer patches arrive.
- Before anything: join the Roblox group and like the game, or codes will not redeem.
- Redeem in game: cog icon bottom right, enter the code, press OK.
- Every code pays Cash, the currency for card packs and roster upgrades.
- Newest and biggest: SORRYFORDELAY10, ten million Cash.
- New codes follow each card update, apology codes pay the most.

If a code bounces, check the group membership and the like first, then consider that update codes retire fast in this game, each new patch tends to kill the wave before last. Whatever replaces these will be here on the next sweep.

Blue Lock Card Battles codes FAQ
What do Blue Lock Card Battles codes actually give you?
Cash, exclusively, and in large amounts. The current wave pays between three and ten million per code, and Cash covers everything that matters: card packs, roster slots, and income upgrades. There are no cosmetic or filler rewards in this game's codes.
Why will my code not redeem?
Nine times out of ten you have not joined the Blue Lock Card Battle Roblox group or have not liked the game, both are required and the error is not always clear about it. After that, check for typos, and finally accept that update codes here die fast once a newer patch arrives.
What should I spend the free Cash on?
Card packs during an event banner, if you are chasing top strikers, or income upgrades if you are playing the long game. The twenty-three million from the current codes is enough to do a bit of both, and income upgrades compound, so they are the sleeper pick for anyone who plays daily.
How often do new Blue Lock Card Battles codes come out?
Every card update brings at least one, and the game patches often, the counter is already past twenty. Events like the current ELO and NEL wave add extras, and delays or bugs trigger apology codes, which historically pay the most. Expect something new every couple of weeks.
Are the apology codes really the best ones?
Consistently. SORRYFORDELAY10 pays ten million Cash, more than double any regular update code in the current wave, and past apology codes like SORRYFORBUGS paid above their era's standard too. Whenever an update slips, keep an eye out, the compensation tends to be generous.
Where do new codes show up first?
The game's Roblox group and Discord announce them with each patch, and trackers like Pro Game Guides and Try Hard Guides mirror them within a day. That pair is what I verify against before anything lands on this list.
