US sports fans in the UK are the target audience of new sportsbook RedZoneSports, which has been launched by Argyll Entertainment.
Punters can visit RedZoneSports.com to bet on the NFL American football league, NBA basketball, Major League Soccer and MLB baseball, with a wide range of betting options and promotions on offer.
The platform also features odds on traditional European sports, such as football, tennis and horse racing.
Stephen Baumohl, vice-president of trading at RedZoneSports, said: “At Redzone we love all sports but we have a particular soft spot for all things American, and especially NFL.
“If like us your heart beats a little faster from September to the Super Bowl you will have noticed that there is very little choice between bookmakers when it comes to betting on American football.
“We believe in creating our own lines and odds for US sports and we are prepared to back that up by having high limits for all customers.”
The launch comes after Argyll last month also rolled out sister site BetOnBrazil.com, backed by broadcaster and former footballer Alan Brazil.
Stuart Tilly, chief executive of Argyll, added: “Following the initial success of BetOnBrazil we want to take our same philosophy of having entertainment at the heart of everything we do and apply it to a US sports-themed gambling destination for the rapidly-growing number of UK customers who follow the NFL, NBA and other major US sports.
“There were three NFL games hosted in the UK this year and the league hopes to have a permanent London team within 10 years; this is a great time for the betting industry to reach out to fans of US sports across the UK.”
