Overview
Mystery Studio was a casual video-game development studio founded in Montevideo, Uruguay, in 2002 by Gabriel Gambetta and Esteban Guelvenzu. The company initially operated under the name Mr.Io Studio, a wordplay that sounded similar to the Spanish word "misterio," meaning mystery, before adopting the Mystery Studio name. Its work was directed primarily toward downloadable casual games, while also including contracted programming and development assignments for publishers and other game companies. The studio became best known for Betty's Beer Bar, released in 2003. The game adapted the basic serving-and-customer-management idea associated with Tapper into a casual-game format built around multitasking and service workflows. Its approach helped establish a recognizable category of serving and multitasking games, a format later associated with successful casual titles such as Diner Dash and Mystic Inn. Mystery Studio's portfolio therefore included both original intellectual property and work performed for external developers, publishers, and license holders. During the middle and late 2000s, the company expanded beyond its best-known original title. Its projects included original casual games such as PegSweeper, FaceIt, Wild West Wendy, Pigllionaire, Cathy’s Caribbean Club, Breaking News, Fashion Assistant, and Lavender's Botanicals. It also participated in licensed and externally originated projects, including CSI: New York, Murder, She Wrote, The Lost Cases of Sherlock Holmes, Brain Spa, The Conjurer, and Real Detectives: Murder in Miami. In several of these cases, Mystery Studio was credited primarily with programming while another company handled development, licensing, or publishing. A notable business relationship was its 2006 partnership with PlayFirst on Pirate Poppers, a dynamic match-three puzzle game developed by Mystery Studio and distributed by PlayFirst. The title was reported as reaching the top ten in both downloads and sales on major downloadable-game channels, giving the studio visibility beyond its earlier serving-game success. Mystery Studio also worked with publishers and partners including Ubisoft, uClick, Legacy Interactive, and FreezeTag on different projects. Technology and production practices were closely associated with Gabriel Gambetta, identified as the studio's director and chief technology officer. He was described as a Linux advocate and developed the studio's games under Fedora Linux, cross-compiling them for Microsoft Windows and Mac OS X, the platforms on which the games were sold. This technical approach allowed a small Uruguay-based team to support commercially distributed games across multiple desktop operating systems. Mystery Studio closed in 2011. The available account links the shutdown to Gambetta's relocation from Uruguay to Zürich and his acceptance of a position at Google. No successor company, continuing parent organization, or later operating activity is identified in the cited material. The studio's enduring significance rests on Betty's Beer Bar, its contribution to the serving and multitasking casual-game format, and its role as a development and programming partner on a range of licensed downloadable games.
History
Mystery Studio was established in Montevideo in 2002 by Gabriel Gambetta and Esteban Guelvenzu. Its original name, Mr.Io Studio, was chosen as a sound-based reference to "misterio," the Spanish word for mystery. The studio developed both first-party games and projects made for external publishers or development partners. Its breakthrough title was Betty's Beer Bar, released in 2003. The game reworked the serving concept associated with Tapper for the casual-download market and emphasized the simultaneous management of customers and service tasks. The title helped popularize a form of casual multitasking and serving game that later included better-known releases such as Diner Dash and Mystic Inn. Mystery Studio continued to produce original casual games while taking on programming and development assignments. Its original or studio-led releases included PegSweeper, FaceIt, Wild West Wendy, Pigllionaire, Cathy’s Caribbean Club, Breaking News, Fashion Assistant, and Lavender's Botanicals. Its contracted work included programming for licensed properties and projects developed by other companies, including CSI: New York, Murder, She Wrote, The Lost Cases of Sherlock Holmes, Brain Spa, The Conjurer, and Real Detectives: Murder in Miami. In 2006, Mystery Studio worked with PlayFirst on Pirate Poppers. Mystery Studio developed the match-three puzzle game and PlayFirst distributed it. The title was described as performing strongly on major downloadable-game channels, reaching the top ten for both downloads and sales. Other credited relationships included Ubisoft, uClick, Legacy Interactive, and FreezeTag, with the studio's role varying between development and programming. Gabriel Gambetta served as director and chief technology officer. He was associated with Linux development and reportedly created the games under Fedora Linux before cross-compiling them for Windows and Mac OS X. Although the production environment was Linux-based, the commercial releases were offered on Microsoft's desktop platform and Apple's Mac operating system. The studio shut down in 2011. The cited explanation connects the closure to Gambetta's move from Uruguay to Zürich and his acceptance of employment at Google. The available material does not identify a new owner, successor, or continuation of Mystery Studio after the closure.
