I Sioux was founded on 01/01/2001, starting as a media company, developing websites and multimedia applications for (media)partners.
Within a couple of years, people within the company started to develop games, first just for fun, but very soon, they got more serious with it. The games turned out to be quite successful worldwide and I Sioux Media Productions decided to explore the world of games. At this moment the company decided to focus on casual games only. In 2007 the company was divided in two separate divisions. I Sioux Game Productions was born. In the last couple of years the company has grown fast and more and more quality games have been developed. All games are published under the Youdagames brand, which has become a well known brand in the international casual games industry now.
