Maddie has inherited a mansion. Her Grandma Ursula helped her get it. Grandma Ursula is not what she appears. The mansion has secrets. The garden has secrets. Even the items on the merge board seem to be hiding something.

Merge Mansion is a merge puzzle game with a renovation narrative, in which the player combines matching items on a grid to produce higher-tier objects that are then spent on restoring a crumbling mansion and its grounds. The merge chains progress from basic tools through to finished renovation materials, and managing the limited board space while generating the specific items needed for each task is the core strategic challenge. Narrative scenes between Maddie and the cast — particularly the enigmatic Grandma Ursula — advance a mystery storyline that distinguishes the game from purely mechanical merge competitors. An energy system regulates play pace. Seasonal events introduce limited-time merge chains and exclusive renovation items. Merge Mansion achieved rapid growth after launch, supported by Supercell's investment in Metacore and a series of viral advertising campaigns featuring Grandma Ursula's increasingly suspicious behaviour that became a cultural moment in mobile game marketing.
