What cash does in Blue Lock Card Battles

Cash is the core currency across Blue Lock Card Battles. It buys card packs from the shop, expands your active roster of players, raises your income per second, and boosts the ratings you pull from 15-second claim rolls. Redeeming codes gives you a head start on all of these without having to grind through match after match to build up a balance.

Where to find new codes

New codes typically arrive alongside card updates, seasonal events, or milestone celebrations. The official Blue Lock Card Battles Discord server is the most direct place to catch announcements as soon as the developers post them, and the Roblox group linked above also shares drops. Checking back here periodically works too, since this list gets refreshed whenever a new code goes live or an old one stops working.

Codes are case-sensitive and typically only work for a limited window, so it pays to redeem a fresh code as soon as you spot it rather than saving it for later.
