UK-listed game developer GameAccount Network has signed a partnership to launch a free-to-play online casino for Oklahoma casino operator Osage Casinos.

Osage Casinos is owned by the Osage Nation, and comprises seven casino properties in the state of Oklahoma including Hominy, Pawhuska, Sand Springs, Tulsa, Bartlesville, Skiatook and Ponca City.

It is the first deal under GameAccount’s strategic partnership with Konami Gaming.

Osage Casinos will be the first internet gaming system connected to the Konami Synkros Casino Management System, with a “promotional play” online casino expected to be launched during the second half of this year.

“There is a significant opportunity within Oklahoma State and throughout the US to grow the Osage Casino brand online,” said GameAccount Network CEO Dermot Smurfit. “We are delighted to partner with Osage Casino who will be our first Konami customer. This partnership follows our successful launch of the first ever simulated online casino in the US in February 2014.”

The free-to-play online casino will include Osage Casinos’ land-based casino games, and will be available to players across multiple platforms including desktop, Android phones and tablets, iPhones, iPads, and mobile formatted browser-based play.

Shares in GameAccount Network plc (Co. Data) (AIM:GAME) are currently trading at 138.50 pence per share in London this morning following the announcement.
