Seriously Digital Entertainment Oy is a mobile game development company, renowned for creating the globally successful puzzle adventure game, 'Best Fiends.' Founded in August 2013 by former Rovio executives Andrew Stalbow and Petri Järvilehto, the company focused on building high-quality, character-driven mobile entertainment with a strong emphasis on IP development. Their flagship game, Best Fiends, launched in October 2014 and quickly garnered a massive global following. In 2019, Seriously Digital Entertainment was acquired by Playtika, a leading mobile gaming company. Seriously now operates as a key studio within Playtika, continuing to support and evolve the Best Fiends franchise, leveraging Playtika's global resources and expertise in live operations and monetization.
Primary game development, art and animation, creative design, sound engineering, and original operational headquarters for the Best Fiends franchise. Now functions as Playtika Helsinki, focusing on Best Fiends development and operations.
Likely a modern, open-plan office space designed to foster creativity, collaboration, and innovation, characteristic of Nordic tech and gaming companies. Features would include state-of-the-art development tools and comfortable amenities for employees.
Originally known for a passionate, ambitious, and creative start-up culture focused on producing high-quality mobile games with strong narratives and memorable characters. As part of Playtika, the studio culture integrates with Playtika's data-driven and performance-oriented approach while aiming to retain its creative core.
The Helsinki office was the birthplace and nerve center for the creation and initial global scaling of the Best Fiends universe. It represents a success story in the Finnish mobile gaming ecosystem, known for producing global hits.
As the creators of the globally popular 'Best Fiends' mobile game, Seriously Digital Entertainment achieved a significant worldwide player base with its games available in numerous languages on major app stores (iOS and Android). Post-acquisition by Playtika, its global reach and operational capabilities are substantially amplified through Playtika's extensive international infrastructure. This includes localized marketing, multi-language customer support, global live operations for Best Fiends, and access to Playtika's worldwide user acquisition networks and data analytics platforms.
