Code	Reward	Did it work?

How this list is checked: developers announce codes in-game and on their Discord, X and YouTube channels. We cross-check those announcements against several independent code trackers and list a code only when at least two confirm it works (last checked 1 November 2026).

SINGLE VOICE for strings: only Pro Game Guides (GAMURS) publishes them: FIVEDOTFIVEK?!, FIVETHOUSAND, 4POINT5K, SORRYGENO4, ERRORUPDATE, 1MILVISITS, 3200LIKES, SUMMER2022, REMZEROVERSE, FREEGOLD, GENOFRISKISBALANCED, EchidenpaiBrokeTheGAme2, FREESOULS, SmallBoost (expired per the same page: SORRYGENO2, SORRYGENO). The plainconnection page is a verbatim reprint of the Pro Game Guides list, not a second voice. Roblox Den reports 8 active / 31 expired but corroborates counts and rewards only. Nothing staged until an independent second list appears.
