You Don't Know Jack (commonly abbreviated YDKJ) is a series of computer games developed by Jackbox Games (formerly known as Jellyvision Games) and Berkeley Systems, as well as the title of the first game in the series. YDKJ, framed as a game show "where high culture and pop culture collide", combines trivia with comedy. While primarily a PC and Mac-based franchise with over two dozen releases and compilations for those platforms, there have been a few entries released for consoles: two for the original PlayStation, and the 2011 release which had versions on the Xbox 360, PlayStation 3, Nintendo DS and Wii. In 2012, Jackbox Games developed and published a social version of the game on Facebook with cross-platform versions subsequently released for iOS, Android and Kindle. On November 5, 2013, the majority of the franchise’s many volumes and spinoffs were reissued onto Steam by Jackbox Games.
