About Undertale Adventures X codes and updates

Four strings are active. GamesRadar on October 19, 2026, Eurogamer on October 18, 2026, UrGameTips on October 22, 2026, and TechySnoop on October 24, 2026 list PREPAREFORHALLOWEEN, 5KCCUREWARD, and 6KCCUREWARD. PREPAREFORHALLOWEEN pays 25x Soul Fragments, 10x Temmie Flakes III, 1x Bravery Vial, 5x Gaster Hands, 1x Temmie Flakes IV, 10x Perfect Souls, 1,023 Souls, and 1,023 Gold. 5KCCUREWARD and 6KCCUREWARD grant the same reward bundle: 50x Trait Rerolls, 15x Gaster Hands, 5x Glamburger, 1x Temmie Flakes V, 5x Face Steak, 1x Butterscotch Pie, 1x Abandoned Quiche, 5x Ketchup, 1x Legendary Hero, 5x Starfait, and 5,555 Souls. GamesRadar, TechySnoop, and MrGuider on October 23, 2026 list MOREFREESTUFF for 25x Trait Rerolls, 3 Gaster Hands, and 1,000 Souls. The developer has not announced an expiration date. Codes are case-sensitive, including the ! character.

FREETOKENS and HALLOWEEN2026! stay in Verifying and do not get a copy-as-working button. MrGuider and undertaleadventuresx.wiki list FREETOKENS for 5 Spooky Goodie Bag and 1,500 Jack-O-Tokens. Our verification check notes that those two lists are the only ones among the checked majors. HALLOWEEN2026! is the MrGuider string. The wiki prints Halloween2026!. Our verification check treats that a case conflict with single-tier sources, so neither casing is published as active. UrGameTips on October 22, 2026 is cited on the active cards. Our verification check notes that that page is partially stale on expired strings, so the expired set comes from GamesRadar, Eurogamer, and the wiki. Older Pro Game Guides and Destructoid tower-defense pages from 2025 are not used as sources. 2KCCU!, FREESTUFF!, TRADINGSOON!, MONEYTONIGHT, THANKYOUFORWAITING, 3KCCU!, 4KCCU!, UAXISTHEBESTUTTD, UPDSEP25!, XMASUPDATE2025, HOTLANDS2025, JUNE10UPDATE, UPDATEJUNE10, THANKYOU10kMEMBERS, THANKYOU12MILLIONVISITS, SORRYAFTERTALEDELAY, WELOVEUAPLAYERS, and WINTER2025 are expired. Click the Codes button on the right side of the lobby, paste the string, and press Enter. The October 24, 2026 snapshot showed 6,336 players, 20,687,658 visits, and 44,015 favorites. Side Productions updated the experience on October 24, 2026.
