Mr Green is to branch out of being a casino-only operator by going live with its sportsbook ahead of a planned launch.
The plans for the sportsbook were first announced in February, and the operator’s CEO Per Norman told Gambling Insider that the completion of the plans would occur when it could reach agreement with a third-party supplier.
Kambi was confirmed as the sportsbook provider in April.
The sportsbook launch coincides with UEFA Euro 2016, which begins on Friday.
Norman said on Tuesday: “By launching a sportsbook, we are meeting our customers’ demand for betting and odds.
“We have built a sportsbook of the same high quality as our online casino and I’m happy that we can launch the sportsbook ahead of the European Championship.”
This has been a year of change for Mr Green, which recently moved from the Stockholm Nasdaq list to the AktieTorget list.
