On June 10, 1995, the FSIN First Nation Gaming Act became a reality and a management body was created to develop, conduct, manage and operate on-reserve casinos. That entity was the Saskatchewan Indian Gaming Authority (SIGA). It was incorporated on January 11, 1996, as a non-profit organization.

Shortly after its creation, SIGA opened the doors to four First Nations casinos in Saskatchewan.  The fifth opened eleven years later:

• Gold Eagle Casino, North Battleford, March 1996
• Northern Lights Casino, Prince Albert, March 1996
• Bear Claw Casino, White Bear First Nation, November 1996
• Painted Hand Casino, Yorkton, December 1996
• Dakota Dunes Casino, Whitecap First Nation, August 2007

Finally, SIGA's added its sixth casino, the Living Sky Casino, which opened in late December 2008 in Swift Current.

SIGA is responsible for the daily management and operation of accounting and auditing systems, the conduct of casino activities, the procurement and maintenance of gaming equipment and the casino's game delivery, in addition to security and surveillance.
