Mobile Deluxe

Mobile Deluxe is a mobile game developer and publisher based in Santa Monica, California. Its work focuses on casual games, classic solitaire variations, card games and Sudoku puzzles, alongside social casino titles. The studio develops freemium experiences supported by advertising and in-game social features.

Founded in 2003 by Josh Hartwell under the corporate name GOSUB 60, Inc., the business began developing games for early mobile platforms before modern smartphone app marketplaces emerged. Its initial work included carrier-deck games, establishing a history in mobile entertainment that predates the distribution model now associated with the Apple App Store and Google Play. Mobile Deluxe subsequently became its primary consumer-facing brand.

The studio's catalog developed around familiar game formats adapted for mobile play. Solitaire became a central part of its output, with the Solitaire Deluxe family expanding into multiple variations. Its broader portfolio also includes Sudoku and casino-style games. Across these formats, its capabilities encompass mobile game development, publishing, live operations, advertising monetization and support across platforms.

In October 2021, Murka Games Limited acquired Mobile Deluxe as part of an expansion into casual games and solitaire. Mobile Deluxe continued as an operating subsidiary brand, retaining its focus on specialized casual product development within the wider group. The acquisition connected its established casual games business with Murka's international publishing operations. As of the supplied November 2026 research, Mobile Deluxe remains active under Murka's casual games umbrella.
