Monopoly GO Monster Mash Album runs from September 23rd to November 25th, 2026, and brings a brand new upgrade to the game.
One of the main highlights of this season is Trick or Treat, a new social feature that allows players to visit their friends' boards, choose one of five mysterious houses, and engage in a quick dice duel to win shared rewards.
Unlike traditional milestone events where players simply land on specific squares to accumulate points, Trick or Treat adds a risk-and-reward element to the game.
This guide will provide a detailed overview of Monopoly GO Monster Mash Album Trick or Treat, including how it works, its mechanics, and how to maximize your visit's value. It will help you efficiently complete the challenge and earn rewards.

About Trick or Treat
Trick or Treat is a board raid event launched concurrently with Monster Mash Album. The core concept is simple: you will enter another player's board and choose from five houses. Your goal is to find Treat while avoiding the hidden Ghosts.
This event centers on player interaction, blending randomness, competitive dice battles, and a gift exchange system. The structure of the five houses means that if the hidden house's location is randomized, there's a one-in-five chance of hitting Ghost on each attempt, but the actual mechanics may involve different probabilities.
Trick or Treat no longer solely focuses on dice rolling, building properties, and personal growth; instead, it encourages players to visit friends, exchange rewards, and make decisions during brief board raids.
How It Works?
Step 1: Visit a Friend's Board
You can initiate a Trick or Treat attempt by visiting other players' boards through the event interface. This makes the event social - you're not playing against game AI, but interacting directly with other players' boards.
Step 2: Choose One of Five Houses
Once you enter an opponent's board, you'll see five houses. You must choose one, which is the key decision point of the game. These houses are like a game of hide-and-seek: some houses hide Treat, but at least one house hides Ghost.
Step 3: The Outcome
If your chosen house contains a Treat, the visit continues. However, be aware that a successful selection may trigger a dice duel - a quick competitive mechanic where you and your opponent roll dice. If both roll the same number, both receive a reward.
This mechanic differs from Shut Downs or Bank Heists, where one player's gain comes at the expense of the other.
If your chosen house contains a Ghost, the visit ends immediately. A Ghost represents a trap in Trick or Treat, abruptly ending your attempt with neither a duel nor a reward. However, you and your friend can retain the rewards earned from previously opened houses until the Ghost appears.
Rewards and Gifting Mechanism
Treats won in Trick or Treat fill Luck-O-Lantern's progress bar. Rewards can only be claimed once the bar is full. The rewards are diverse, including Dice, Sticker Packs, and Tokens.
For players focused on completing the season's album, if you're lacking dice or Monopoly GO stickers, actively participating in Tricks or Treats will help boost your album progress.
In addition, Monopoly GO introduces a gifting system, allowing players to exchange gifts with friends. This social interaction transcends the dice duel itself, creating a two-way exchange where active participants gain more than passive ones.
The gifting system complements the duel rewards, reinforcing the season's theme of enjoying time with friends and sharing a little prank.
Strategies and Tips
Collaborating with Friends
The dice duel reward mechanism is clearly reciprocal: the match results in a win-win situation. Therefore, having more active friends is crucial. If you and your friends actively participate, your chances of matching dice and sharing rewards will be higher, leading to a better gaming experience and significantly more efficiency than interacting with random players.
Keep a Sufficient Number of Dice Available
Trick or Treat doesn't deviate from the regular gameplay, so having enough dice will give you more opportunities to access and earn Treats.
Synergy with Luck-O-Lantern
Monopoly GO Monster Mash season introduces both Luck-O-Lantern and Trick or Treat social features.
If the two overlap in the event schedule, you can combine them in a single social interaction: visiting a friend's board might trigger a Trick or Treat, or you might accumulate candy by clearing Lantern railroad squares on the board. This way, you can cover the progress of both features in one action, making it more efficient.
Observe Your Sticker Album
In the early stages of a new album, almost every sticker pack is valuable because you have many empty slots. Later in the season, your strategy should shift towards high-star packs, trades, Gold Blitz events, and missing gold stickers.
That concludes this article on Trick or Treat, an event that brings a whole new social interaction experience to Monopoly GO's Monster Mash Album. It combines a probability-based house selection mechanism with mutually beneficial dice duels and gifting mechanics, creating an interactive experience that encourages collaboration and active participation.
The five-house structure introduces a controlled element of risk - one wrong choice ends the attempt - but the possibility of shared rewards makes it well worth playing with friends. Go try it out now!
