Relax Gaming's Gibraltar branch has received a B2B provider license from the UK Gambling Commission.
Once the game is approved, the companies' online casinos will be made available to UK operators for the first time through Relax Gaming Gibraltar Ltd.
Operators and brands including BoyleSports, 32Red and BetVictor have already been transferred to the company's Gibraltar network, while Entain's UK brands including Ladbrokes and Coral are due to move.
Relax Gaming holds existing licenses with the Malta Gaming Authority, the Gibraltar Licensing Authority, the Romanian National Gaming Office and is separately licensed by the UKGC in relation to its business in Malta.
The company currently offers over 2,000 individual online casino games to B2B partners.
Reflecting on the award of the license, Relax Gaming CEO Tommy Mayala said: “Following a fruitful relationship with UKGC through our Maltese company, the approval of all of our products and services for our Gibraltar affiliate is another major commercial milestone for us.
“Its value will be felt throughout the business, including among our valued third party partners.
“This license acquisition represents a new opportunity in our quest to deliver excellence and growth across all regulated markets,” Mayala added.
