MONOPOLY GO! Monster Mash Season: KPop Demon Hunters & Ghostbusters Crossover Explained

Scopely is closing out spooky season with its biggest crossover yet for MONOPOLY GO!, the mobile board game that the publisher says draws more than 10 million logins a day. Starting September 23, the game's new Monster Mash season pairs a Halloween theme with two licensed collaborations at once: Netflix's KPop Demon Hunters and the Ghostbusters franchise. Here is everything Scopely has confirmed about the new season, its features, and how it fits into the game's board.

1. What Is the Monster Mash Season?

Monster Mash is MONOPOLY GO!'s next themed season, running from September 23 to November 25, 2026. It replaces the Happy Harvest season, which ran a Looney Tunes collaboration from late July through September 23. Like every MONOPOLY GO! season, Monster Mash brings a new sticker album, a fresh coat of visual theming across the board, and time-limited events layered on top of the game's usual dice-rolling and property-building loop.

What makes this one different is the double license: rather than a single collaboration, Scopely is running KPop Demon Hunters and Ghostbusters side by side for the full two-month season, tied together by a Halloween "monster" theme. Victor Diaz-Roig, who leads MONOPOLY GO! at Scopely, described it as "the season of thrills and chills," framing it around playing with friends through the Halloween window rather than around either license alone.

2. Not Scopely's First Big Crossover

MONOPOLY GO! has leaned on entertainment tie-ins for several of its past seasons, which is useful context for how seriously to take a two-license season like this one. The game's official YouTube channel has previously hosted trailers and event content for crossovers including Harry Potter, The Simpsons, Hello Kitty and Friends, and, most recently, Looney Tunes during the Happy Harvest season that Monster Mash is replacing. Pairing two licenses in the same season is a step up in scale, but the format — a themed sticker album plus a handful of limited-time Racers, Partners, and Treasures events — is the same one the game has used for its licensed seasons going back some time.

3. KPop Demon Hunters Crossover: HUNTR/X and the Saja Boys

The first collaboration brings Netflix's animated hit KPop Demon Hunters into the game, with HUNTR/X and the Saja Boys appearing across MONOPOLY GO!'s usual event formats. According to Scopely, the content includes:

• Blocks Boutique — a KPop Demon Hunters-themed shop stocked with digital collectibles tied to the event.
• Racers — a street race through Seoul that leads into the Underworld, one of the film's key settings.
• Partners — a cooperative event where players work together to build KPop Demon Hunters-themed attractions featuring characters like Mira, Rumi, and Zoey.
• Treasures — a HUNTR/X concert experience built around hidden treasures to uncover.

Scopely says this is also the first time MONOPOLY GO! has licensed real songs for its in-game soundtrack: HUNTR/X's tracks "Golden" and "How It's Done" will play during the KPop Demon Hunters content.

4. Ghostbusters Comes to 550 Central Park West

Running alongside it, the Ghostbusters crossover pulls from the franchise's most recognizable locations and gear. Confirmed content includes a rooftop vehicle race around 550 Central Park West — the real-world address used as the Ghostbusters' apartment building exterior in the films — a cooperative Partners event built around Ghostbusters-themed attractions, and a Treasures event that puts players inside the iconic Firehouse armed with the Proton Blaster to uncover rewards while facing off against Gozer.

5. New Head-to-Head Features: Luck-O-Lantern and Trick-or-Treat

Beyond the two licensed tie-ins, Monster Mash introduces two new social features built specifically for playing against friends rather than just alongside them:

• Fill Up Your Luck-O-Lantern — players collect candy while moving around the board and can choose to share it with another player, similar in spirit to MONOPOLY GO!'s existing gifting mechanics but framed around the Halloween theme.
• Trick-or-Treat is Knocking — a head-to-head dice duel where two players each roll, and whoever rolls higher wins a reward from their opponent's stash.

Both are described by Scopely as new mechanics for the game rather than reskins of existing events, so expect UI prompts explaining them the first time they appear on your board after the season goes live.

6. The Mystery Mansion Sticker Album and Community Tokens

As with every MONOPOLY GO! season, Monster Mash ships with a new sticker album — this time named Mystery Mansion — built around classic Halloween monster imagery (think Dracula, Frankenstein's monster, witches, and werewolves) alongside dedicated sticker sets for both the KPop Demon Hunters and Ghostbusters crossovers.

Scopely is also folding in a community element this season: designs that players submitted and voted on through the official MONOPOLY GO! Discord will appear in-game as earnable Tokens, and a community-voted "Wishing Board" design is set to launch during the season as well.

7. Tips for Getting the Most Out of Monster Mash

A few practical notes for Tycoons heading into the new season:

• Log in on launch day. Season-opening days on MONOPOLY GO! typically come with free dice and a batch of easy early album sets, so starting September 23 rather than a week later gives you a head start on both crossover albums.
• Save trades for dedicated sets. With two licensed properties in one album, expect separate KPop Demon Hunters and Ghostbusters sticker sets — trade duplicates within your active friend groups for the set you're missing rather than hoarding everything.
• Watch for time-limited Racers and Treasures windows. Scopely's past seasonal events (like the Happy Harvest/Looney Tunes season before this one) have run their headline mini-games on rotating schedules rather than keeping them open all season, so check the in-game event tab daily.
• Use Trick-or-Treat duels against friends you trade with anyway. Since it is a head-to-head feature, it works best with people already in your regular trading circle rather than random opponents.
