Monopoly GO Monster Mash runs from September 23 to November 25, 2026, with a 22-set sticker album, KPop Demon Hunters and Ghostbusters events, and several ways to earn Halloween rewards with friends.
The seasonal album stays open until November 25, but individual activities come and go. The latest is Monster Mash Partners, running October 21–26 with a Swamp Monster Token among its advertised prizes. Here’s what belongs to the album, what you can earn from events and which dates matter right now.

| Season | Start | End |
|---|---|---|
| Monster Mash | September 23, 2026 | November 25, 2026 |
The season began on September 23 after Scopely’s September 22 announcement. That November 25 end date applies to the album and overall Halloween season; the Partners event has its own, much sooner deadline.
Monopoly GO Monster Mash collaborations: KPop Demon Hunters
KPop Demon Hunters appears across several Monster Mash experiences. Scopely has confirmed Blocks Boutique content, Racers, Partners and HUNTR/X Treasures, with HUNTR/X and the Saja Boys featured throughout.
For the first time in Monopoly GO, licensed songs also appear in the game, including HUNTR/X tracks Golden and How It’s Done.
Ghostbusters content
Ghostbusters receives its own Racers, Partners and Treasures content. The Ghostbusters Partners event ran through October 4 and offered the Slimer Token as its grand-prize collectible.
The Ghostbusters Treasures theme takes players into the Firehouse and uses a Proton Blaster concept to uncover equipment from the franchise.
Monster Mash album: 22 sets and three bonus sets
The Monopoly GO Monster Mash album has 22 main Sticker Sets, containing 198 stickers. Three additional Bonus Sets appear during the season, giving collectors 25 sets in total. You only need the 22 main sets for album completion; the bonuses are optional. Finishing the main collection earns a special token and other rewards.
There’s some confusion over the name because Scopely used two descriptions. Its September 22 announcement called it the Mystery Mansion Album and counted 25 sets, while the detailed season guide calls it the Monster Mash Album with 22 main sets and three optional Bonus Sets. The useful rule for completing the album is unchanged: only the 22 main sets are required. Mystery Mansion is also the setting for Mr. M’s separate Rolling Tales and Scottie Patrol stories.
Luck-O-Lantern
Luck-O-Lantern lets you find Candy in Sticker Packs, minigames, Leagues and on the Color Wheel. Collecting enough Candy fills your lantern and unlocks rewards to share with a friend. Normal album and event play can both contribute to the same seasonal feature.
The choice to keep progress or send it to a teammate belongs to Franken Paths, another team mode introduced during Monster Mash. It isn’t a Luck-O-Lantern feature, so don’t mix up the two reward systems.
Trick-or-Treat dice duel
Trick or Treat is a Railroad activity with five houses: four can hold Treats and one hides a Ghost. Open a Treat house and face a friend in a dice duel for its prize. Reveal the Ghost and your visit ends, but you keep the Treats collected earlier. It’s completely separate from the Partners wheel.
Monopoly GO Monster Mash also adds Hold the Lead to Tycoon Racers, rewarding teams that get ahead and maintain their position alongside the regular championship leaderboard.
Community-designed rewards
Community-created Tokens are another part of the season. Winners from Scopely’s Community Workshop are being turned into collectibles in Community Deluxe Drops, while player costume submissions appear in the Community Gallery Sticker Set.
There’s also a Wishing Board designed through a community vote. These are seasonal additions rather than one-off rewards from the October Partners event.
Monopoly GO Monster Mash Partners: October 21–26
Monopoly GO Monster Mash moves into another Partners event on October 21. Monster Mash Partners is scheduled to begin at 9 PM BST, bringing four shared attractions and a previewed grand prize of 5,000 dice, a Swap Pack and the Swamp Monster Token. The event ends on October 26 at 7:59 PM GMT, after the UK’s October 25 clock change.
The currently reported reward ladder has five cumulative milestones on each attraction, with the final build level at 80,000 shared points. That makes 320,000 points across all four builds. Both currently published event previews list a 30-minute Builder’s Bash at the final milestone, alongside dice, Cash and a four-star Sticker Pack. They differ on the pack quantity, so check the live reward panel for that detail.
During the opening days of Monopoly GO Monster Mash Partners, the October 21 Quick Wins schedule offers 250 Partner Tokens across the three tasks. The Muscle Madness event, running October 21–23, lists 3,780 more across its full milestone ladder. These are potential earnable rewards, not an automatic event-start bonus. The current solo event and tournament pages cover the rotating ways to earn more rolls and event currency.
The October 18–21 Ghostbusters Treasures event is the previous Halloween activity; it is not the new Partners challenge. For the rest of the Monopoly GO Monster Mash season, the free dice links and Golden Blitz guide remain useful alongside the sticker-album events.
The Monopoly GO Monster Mash season carries on after Partners ends, with the album and other rotating activities available until November 25. Keep checking the live game for current events; the Halloween season and the five-day Partners event have different finish dates.
