The deal sees Argyll drop the Amelco platform in favour of SBTech, which the company described as representing a "critical dimension" of its expansion strategy, allowing it to boost brand recognition and increase UK market share.

SportNation launched in October 2016, originally named BetOnBrazil after former footballer and radio presenter Alan Brazil, while RedZoneSports, a US sports-focused offering, launching in November 2016.

"This new partnership with Argyll Entertainment is further evidence of our rapidly expanding footprint in key regulated markets worldwide," SBTech chief product officer Ian Bradley said. "We have extensive experience of driving operators to market-leading positions through our solution and I'm confident that both SportNation and RedZoneSports will now rapidly achieve their full potential.

"I am looking forward to working closely with them on extending our US Sports product with the combined efforts of both teams."

The operator claims that the sites already offer improved price differentiation, and will now be able to offer an enhanced user experience through the Chameleon360 iGaming platform.

It will offer players an improved in-play betting solution, thousands of bet types across more than 60 sports, and other features including flexible cash-out, price boosts and enhanced accumulator betting.

"We are delighted that our family of brands is now powered by SBTech's sportsbook and full platform solution," Stuart Tilly, chief executive of Argyll Entertainment parent company Argyll Partners, said. "The time is right to offer our players a richer offering and a broader range of betting opportunities, boosting the profile of our brands and driving turnover with a more enhanced solution.

"Considering its proven track record for innovation, unrivaled live betting and deep knowledge of British, American and global sports, SBTech was the clear choice moving forward."
