The campaign that got the internet asking “What’s Grandma Hiding?”
-
Since its launch in 2020 Merge Mansion has relied heavily on its storyline featuring family drama and mystery revolving around a condemned mansion and secretive Grandma Ursula.
This rich lore combined with 3D animated ads that raise more questions than give answers have earned the game a devoted fan following and cult like internet status.
But in order to break out of niche internet fame we needed to get the masses interested in “What’s Grandma Hiding?”
-
We leaned heavily on the game’s proven recipe for success but spiced up the lore by introducing a new character – a hard-boiled detective faced with the toughest case of his career.
Enter Tim Rockford, played by Pedro Pascal, our star investigator who would steer the Internet's attention to the mystery at the heart of the game.
Then we took our fans and the Internet at large for on an entertainment and reality-bending ride across platforms.

Be warned, there has been a lot of content created for the campaign. Luckily, you can get a comprehensive overview without viewing all ads and videos.
TEaser
“Hide your knives. There’s a new detective on the Merge Mansion case. Guess who? #WhatsGrandmaHiding”
The first clues of the new character and Pascal were shared on Merge Mansion’s social channels. In a matter of minutes, he was recognized just from his backside - and the rumor mill started churning.
It’s almost like some Twisted Game
“Honestly, I don’t even know where to start.”
The first film of the campaign, a movie trailer resembling A Twisted Game was released on the weekend of HBO’s The Last of Us also starring Pascal.
Soon after it was followed by two other films: Think Like a Grandma and A Recipe to Die For, which deepened the story even further.
The three films have been viewed on YouTube alone more than 38 million times.
“Y’all got pedro!?”
The Internet. Went. Nuts.
The films didn’t just make a splash; they released a tidal wave of reactions that plastered every social platform – recruiting millions of investigators from around the globe.
“Some pretty insane marketing. People have been talking about this non-stop.”
The reactions to the films ranged from incredulous to praising.
For example, YouTuber Danny Gonzales, who has over 6 million subscribers, joined the discussion by creating a humorous 10-minute-long reaction video, accumulating over 2.8 million views.
But that was just the start…
Every family has secrets - But few have a mansion full of them…
After the release of the films, Pascal was joined by celebrity detectives, content creators, and a handful of lucky super fans for an on-site investigation inside the mansion.
Part live-action theatre meets escape room, and part Instagrammable lore museum on steroids, the guests were immersed into the world of Merge Mansion.
The surreal adventure which blurred the line between entertainment and reality was filled with easter eggs and clues that would reveal highly coveted details about the lore and where the storyline would develop next.










What! IS! grandma! hiding!!!?
Even before the post-event cinematic above, the experience was broadcast to the world through the participants’ social channels.
Participants for the event were specifically chosen to align with the themes of the game, with an emphasis on influencers whose followers predominantly consist of so-called casual gamers, a category encompassing the majority of mobile game players.
Among the attendees were familiar faces such as Jesse Williams from the series “Only Murders in the Building” and Ashley Benson from “Pretty Little Liars.”
Notable content creators included for example Ryan Bergara and Shane Madej, known for their work on the BuzzFeed web series "Unsolved Crimes."
“What do you think, Detective Madej?”
In addition to live feeds and stories, the participants created post-event summaries and theorized about What's Grandma Hiding? on their accounts.
A notable highlight was a 16-minute YouTube video (below) by Mathew Patrick, known as The Game Theorist, where he shared his theory with his 18.8 million subscribers.
To save the judges some time, we can reveal that, according to his theory, Ursula murdered her husband and chopped him up into a pie. However, we cannot disclose whether the theory is accurate or not...

Mobile game data is guarded as closely as state secrets—or in this case, Grandma Ursula's secrets. However, a rough estimate of the campaign's success can be inferred from the fact that, after the campaign's release in March 2023, the game's downloads surpassed the 50 million mark, up from under 45 million earlier in the year.
In total, the campaign garnered over 1 billion impressions across various platforms and more than 300 press hits globally. The three films featuring Pascal amassed 38 million views on YouTube, received over 218,000 likes on TikTok, and garnered 891,000 likes on Instagram.
But most importantly, fans worldwide were obsessed with the campaign, joining the investigation to search for answers and share their theories, even igniting rumors of an actual Merge Mansion Movie.
“A central goal for all of our game marketing is to speak to our audience and start conversations around the game, its story and its central characters. Based on fans’ reactions to the campaign and the stir it’s caused, it definitely seems like we’ve met if not exceeded those expectations.” - Sandra Fenyo, VP of Marketing Metacore
But what about the most important question: "What's Grandma Hiding?" Unfortunately, the only way to get answers is to download Merge Mansion and uncover the secrets for yourself. 🤷♂️
