Metacore

Metacore is a Helsinki-based mobile game developer and publisher focused on casual puzzle games and live-service operations. Founded in 2014 by Mika Tammenkoski and Aki Järvilehto, the company began as Everywear Games, developing games for smartwatches before shifting toward mobile casual titles in 2018. It adopted the Metacore name in 2020, alongside the global launch of Merge Mansion.

The studio's flagship game combines merge-2 puzzles with mystery storytelling, character development and home renovation progression. Its ongoing development brings together game engineering, design, narrative and live operations, supported by community management and player support. Metacore's capabilities also include free-to-play game design, monetization management and in-house performance marketing and creative production.

Games and storytelling

Merge Mansion is the central focus of Metacore's current development work. Beyond its puzzle mechanics, the game uses an unfolding mystery and recurring characters to connect play with a broader narrative. Its advertising has extended that storytelling into live-action campaigns featuring actors including Pedro Pascal and Kathy Bates. By mid-2026, the game had accumulated more than 65 million downloads worldwide.

The company's earlier work includes Runeblade, released for Apple Watch in 2015, and the wearable games Time Buzz and Field Day. These projects reflect its origins in smartwatch gaming before its transition to mobile entertainment. Metacore also acquired the rights to Supercell's discontinued farming game Everdale in January 2023 and worked on a revised prototype. That development ended in September 2024, when the rights were returned.

Current direction

Following a period of international expansion, Metacore restructured in 2026 to concentrate its development resources on Merge Mansion. Its continuing Helsinki team handles the game's engineering, design, narrative and live operations. Supercell completed its acquisition of the company in October 2026, and Metacore continues operating within its portfolio. The studio's current direction centers on sustaining and developing its established mobile game through ongoing content, storytelling and player engagement.
