What this guide can confirm
Blue Lock Farm’s official Roblox listing identifies Finding Illusions as the creator and describes a loop of opening Blue Lockers, placing characters, earning money, upgrading characters, and purchasing better lockers. This page avoids unverified prices, odds, and tier claims.
Use the live game as the final check
Move to a better locker when the live pool is more useful than another small upgrade. Open the relevant in-game panel before spending. If a label, condition, or reward differs from an older guide, trust the current game prompt and the official experience.
Practical next step
Record what changed in your own session, then use the related wiki pages to decide whether a character, locker, grade, token, or upgrade is the real bottleneck.
