Undertale RNG Codes Checked 1 November 2026

Undertale RNG — official Roblox game image

Undertale RNG is a rolling game where you spin for custom auras inspired by Undertale and Deltarune, then complete missions, craft gear, and use aura abilities. Only one tracker currently maintains a fresh list for this game, so no code can be confirmed by two sources right now — the current Halloween codes are listed as worth trying below and are dated to expire on November 5.

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).

housesfixesmap, trickorpumpkin and halloweenpass are listed by the one fresh tracker only (all three dated to expire November 5), so they are not counted above — but they are very likely worth trying before then.
