Are these codes still valid?
The June 2024 list does not establish present-day validity. As of October 8, 2026, the official Roblox description still names JOINED, while third-party trackers are not fully consistent: Roblox Den lists JOINED and Thirdfloor as active but marks variants such as OPTIMIZATIONSells, JOINED150, thirdfloor200, and OPTIMIZATION as “Check”; Try Hard Guides lists JOINED and Thirdfloor. Those listings are not proof of successful in-game redemption, and no code was tested in-game for this article. Roblox game page · Roblox Den · Try Hard Guides
If a listed code is rejected, check its capitalization and spelling, then treat the result as unconfirmed or expired rather than assuming a similarly named variant is valid.
