What Cash does in Blue Lock Card Battles
Cash is the main currency for progression. It buys card packs from the shop, expands your active roster, increases your income per second, and raises the rating of your 15-second claim rolls. Grinding PvP and bot matches earns Cash naturally, but redeeming a working code gets you a seven-figure boost without playing a single match.
Where new codes get announced
New codes typically surface in the Blue Lock Card Battles Discord server, where developers post announcements and players share drops as soon as they go live. The in-game Roblox group is another reliable place to watch, since group-exclusive codes sometimes appear there first.
We check for new codes regularly and update the working list above as soon as fresh ones drop, so bookmarking this page is the fastest way to stay current without digging through Discord channels yourself.
