Joker was founded in May 1992 under the wing of Moj mikro. The first edition was duotone and because of poor sales it was cancelled. In September 1993 it was revived as a half-sized addition to Moj Mikro. In January 1994 it had grown in to an independent magazine of full size format. A compact disc was added in December 1995 and a website was launched in March 1996. In December 2000 Joker became the first Slovenian magazine to include a DVD with every copy.
A team member of game development studio Dawn of Play previously worked as a journalist for the magazine.
