PlayKit: Embeddable Game Catalog

PlayKit lets any app add a games section without building or hosting a single game. A host app integrates a thin SDK — a Swift Package on iOS, a Gradle module on Android, or a plain iframe with the same JS contract on Web — and PlayKit's backend serves the catalog, versioned game bundles, matchmaking, live multiplayer state, and anti-cheat. The catalog spans puzzles, quizzes, arcade classics, and real-time multiplayer titles like Chess, Ludo, 13-card Rummy, Uno, Sea Battle, Draw & Guess, and Trivia Royale, alongside single-player games like 2048, Snake, and Solitaire. Live at playkit.in with a public catalog anyone can browse and play directly in the browser, plus integration guides for all three platforms and an admin panel for managing the game roster.
