The company operates a portfolio of five free-to-play social and mobile games: Solitaire Social (the company's flagship and described as the top-grossing web card game globally with 10M+ downloads), Mahjong Social, Yatzy Social, Golden Prairies, and Merge Tale. The games target the broad casual gaming segment and collectively serve more than 300,000 daily players, with multiple titles ranked in the Top 15 (and some Top 10) Grossing games on Facebook.

The company's technology stack is built around multi-platform social and mobile casual gaming, hosted on AWS and integrated with third-party providers across the value chain: Apple Pay, Google Play In-App Payments, and Xsolla for payment processing; Facebook/Meta for publishing and social authentication; AppsFlyer and App Annie for analytics; Helpshift and Zendesk for customer support; Pushwoosh for email marketing; and Google Ads for remarketing. The platform architecture supports PvP tournaments, leaderboards, in-game events, and social features designed to drive engagement and retention.

Kosmos monetizes through a freemium model combining in-app purchases of virtual currency (e.g., 'war bonds', 'crystals') and virtual goods, alongside in-game advertising (interest-based, contextual, and generic formats delivered through partners such as Google Ads). All virtual items are non-refundable, non-transferable, and have no real-world cash value. The company is privately held with no disclosed funding rounds, no parent company, no acquisitions, and no management team information publicly available in the provided data.

Broad incumbents

• Rovio Entertainment (SEGA): Casual mobile games publisher (Angry Birds franchise). Comparable on casually-positioned mobile games distributed across app stores; larger scale and broader IP portfolio.
• Voodoo: French hyper-casual and casual mobile games publisher with billions of downloads. Comparable on mobile UA scale, casual monetization, and platform-store distribution, though more ad-monetized than Kosmos.
• Big Fish Games (Churchill Downs): Long-running casual PC and mobile games publisher with a strong card/solitaire and hidden-object catalog. Comparable on casual card-game portfolio and broad-platform distribution.
• King Digital Entertainment (Activision Blizzard): Publisher of Candy Crush and a large portfolio of casual/social mobile games. Operates at much larger scale but directly comparable on casual-mobile distribution, monetization, and live-ops execution.

Direct peers

• Zynga (Take-Two Interactive): Former standalone social and mobile casual games leader (Solitaire, Words With Friends, CSR); direct peer operating card, word, and match-3 titles across Facebook and mobile. Acquired by Take-Two in 2022 but historically the closest comp for Kosmos’s social-card portfolio.
• Playtika: Public mobile/social casino and casual games publisher (Slotomania, House of Fun, Solitaire Grand Harvest). Direct comp on social-casual card games, live-ops monetization, and Facebook/UA strategy.
• G5 Entertainment: Public, Stockholm-based casual and hidden-object/puzzle mobile games publisher with similar company size and revenue band. Highly comparable on mid-sized social mobile game studio economics.
• MobilityWare: Long-standing mobile card and solitaire developer behind the original Solitaire, FreeCell, and Blackjack apps on iOS/Android. Closest peer to Kosmos’s Solitaire Social and card-game focus.

Emerging players

• Moon Active: Private Israeli hit-driven casual/mid-core mobile studio behind Coin Master. Comparable on social features, live-ops cadence, and reliance on Facebook + mobile distribution.
• Deca Games: Israel-based acquirer and operator of live casual/mid-core mobile games, including card and arcade titles. Comparable on portfolio of older live games and ad/IAP monetization.
