Betsson is relatively new online bookmaker, but only compared with the rest of the online sports betting firms listed here. It was established in 2002, the same year it was granted a bookmakers license in London and began targeting broader market, adding English to the original Swedish version of the website, soon to follow with German, Finish and many more languages. And although this online bookmaker caters to many European countries today, it remains dedicated to serve the UK and Swedish punter with vengeance. And with its sizable free bets offer and  a variety of ways to gamble, including casino, poker and games, besides the sportsbook, Betsson is a good choice for any bettor in the European Union. The reason we gave this online bookmaker rating short of the full five stars is the lack of attention to the Asian and Australian customer. But if you are in the UK or rest of Europe and are looking for a quality online bookmakers, Betsson is a fine choice.

With the addition of CentreBet on our best online bookmakers ranking list, we welcome the Aussie sportsbook of choice. This betting firm was first licensed as a sports bookmaker in 1992 and has quickly became the top choice for Australian bettors to bet on sports online. With the great success Centrebet has experienced in the Southern Hemisphere the sportsbook has focused on expanding its market share to include UK and the EU, which is much welcomed news for the European punters. What really distinguishes this sportsbook from any other online bookmaker is the ability to place large bets. How large? Well, the bookmaker doesn't actually posts its highest bets, but many people have claimed to bet in the tens of thousands on a single slip. If you are lucky enough to be able to afford large sports bets, no better bookmaker than Centrebet.

Canbet is yet another Australian sportsbook, offering a wide variety of sports to bet on, along with poker and casino games. What makes this online bookmaker stand up is the fact that it's owned by the Australian IAS - the first bookmaker to trade publicly on the country's market. With such history, all punters are safe and secure when betting at Canbet and the sportsbooks even allows Canadian and Chinese residents to open a betting account, something hard to find these days. Bonuses and free bets are in abundance with this online bookmaker, ranging from deposit bonus all the way to English Premier League – Second Chance Specials. A sportsbook worthy of being part of our best online bookmakers selection.
