Betsson, Betsafe, Nordicbet and Triobet are brands of the Betsson AB group currently all using the same sportsbook platform.
With exception of few cases concerning local regulations in some countries our principal recommendation is Betsson
The only brand of the Betsson group licensed by the UK Gambling Commission and accepting UK players is Betsafe
The two brands (local sites) licensed in Denmark are Betsafe
Users from Norway, Sweden and Finland are accepted in all brands of the Betsson group but we recommend Nordicbet
which is tailored specially for the Scandinavian market (not accepting players from any other countries) for the bit higher odds and best signup bonus.
