What eureka studio does

Eureka Studio Inc. is a Japanese mobile game studio founded in 2018 that develops and publishes free-to-play hyper-casual and casual games for iOS and Android devices worldwide. Its portfolio of more than ten titles spans puzzle games (Map Fit world-map jigsaw, Draw Bridge physics puzzles, Tidy Roll), escape/skip games (Skip School!, Hide My Test!, Super Prison Escape!, Skip Work!), simulations (Mr. Shipping!, Make a Prison), and adventure games (Purify the World). Map Fit is the lead franchise, having surpassed 80 million cumulative global downloads and topped Google Play worldwide charts. The studio operates a fully remote organization with flextime, develops new game concepts in roughly two-week prototyping cycles, and validates them using CPI and other advertising-metric A/B tests before committing to scale. Core technology is built on the Unity engine; Map Fit in particular uses an algorithm-based automatic puzzle generation system that reportedly reduced per-stage production time by 10x, paired with a proprietary multi-sensory UX layer (visual shadows, snap placement, progressive audio, device vibration).

Revenue is generated entirely through a freemium model combining in-app purchases of virtual items/currency and in-game advertising, the latter served through a stack of 16+ advertising and analytics SDK integrations (AppLovin, Google, Unity Ads, ironSource, Facebook, Adjust, Mintegral, Vungle, Pangle, Tapjoy, Smaato, Adcolony, Fyber, i-mobile, Inmobi, F@N Communications, GameAnalytics). Distribution is exclusively direct-to-consumer via the Apple App Store and Google Play, with device-aware routing from eurekastudio.co.jp. The company has no disclosed external investors, no parent company, and no disclosed revenue figures; ownership appears founder-led. The studio maintains GDPR-compliant data handling with a named Data Protection Officer (Hoshikawa Tetsushi), enabling continued EU/UK/Switzerland operations, and has signaled intent to expand into China/Asia via a partnership conversation with TYKONO at Tokyo Game Show 2024.

Direct peers

• Rollic: Turkey-founded hyper-casual publisher acquired by Zynga. Comparable for its free-to-play puzzle/casual titles and similar scale of downloads, but now backed by Zynga's resources.
• Supersonic Studios: Israel-based hyper-casual studio (previously owned by Unity) with broad free-to-play mobile puzzle portfolio. Comparable for its Unity-based engine and global app store distribution.
• Homa Games: Paris-based hyper-casual publisher with Homa Lab platform used to validate prototypes using CPI/data metrics. Closely comparable to Eureka's 2-week data-validated prototyping loop.
• CrazyLabs: Israel-based hyper-casual publisher (formerly TabTale) with a global portfolio of casual games. Comparable for its publisher-developer model and reliance on App Store/Google Play distribution.
• SayGames: Belarus-based hyper-casual publisher known for rapid concept testing and high-volume UA. Comparable for its data-driven prototyping approach and similar free-to-play, ad-monetized portfolio.
• Voodoo: Paris-based global leader in hyper-casual mobile games with billions of downloads across hundreds of titles. Directly comparable as the dominant category benchmark Eureka is measured against.
• Playgendary: Belarus-based mobile game developer with hyper-casual and casual titles. Comparable as a smaller international peer with similar Unity-based, ad-supported free-to-play portfolio.
• Kwalee: UK-based hyper-casual publisher with hundreds of millions of downloads and an in-house ad-tech platform. Comparable for its data-led hit validation methodology.

Broad incumbents

• Zynga: US-listed major mobile gaming publisher and owner of Rollic. Broader incumbent overlap with Eureka's free-to-play, ad-and-IAP monetized mobile puzzle audience, but at vastly larger scale and portfolio breadth.

Emerging players

• Good Job Games: Turkey-based hyper-casual studio with comparable scale and free-to-play mobile puzzle focus, but smaller portfolio and less chart presence than Eureka's Map Fit.
