Online gambling has become one of Europe’s biggest digital industries, driven by mobile apps, live streaming and a boom in in-play betting on football, tennis and more. The business behind it is increasingly sophisticated: data, pricing models and global sports rights now shape how operators compete, as the rise of data-driven football clubs and the battle for sports streaming show.
For players, the most important factor is safety. Always choose an operator licensed in your country, such as by the UK Gambling Commission or the Malta Gaming Authority, and use the deposit limits and time-outs they provide. These are ten of the most established names. Availability varies by country.
1. bet365
One of the world’s largest online gambling companies, Stoke-based bet365 is known for its huge range of sports markets, strong in-play betting and live streaming of thousands of events. It also offers a full casino and poker product, making it a one-stop platform for many players.

Subscribe2. Betfair
Betfair pioneered the betting exchange, where customers bet against each other rather than the bookmaker, often securing better odds. Owned by Flutter Entertainment, it also runs a traditional sportsbook and casino, and is a favourite with experienced bettors.
3. William Hill
One of Britain’s oldest bookmaking brands, William Hill combines a long high-street heritage with a modern app. Now part of Evoke, it offers a broad sportsbook, casino games and strong coverage of horse racing and football.
4. Paddy Power
The Irish bookmaker is famous for cheeky marketing and promotions, but behind the jokes is a polished sportsbook and casino. Also owned by Flutter, Paddy Power is especially popular for football and racing in the UK and Ireland.
5. Sky Bet
Sky Bet is one of the UK’s most popular betting apps, closely tied to football through its long sponsorship of the English Football League. Now owned by Flutter, it is known for its simple app and its range of football bet builders.
6. Unibet
Part of Swedish-founded Kindred Group, now owned by La Française des Jeux, Unibet operates across many European markets. It offers a strong sportsbook, casino and poker, and has a reputation for responsible gambling tools.
7. 888
888 is one of the best-known names in online casino and poker, with a history stretching back to the late 1990s. Now part of Evoke alongside William Hill, it offers a wide selection of casino games and a well-established poker room.
8. Betway
Betway is a major international brand with a strong presence in esports and football sponsorship. It offers a sportsbook, casino and live casino, and holds licences in several European markets, including the UK and Malta.
9. LeoVegas
Swedish-founded LeoVegas built its name as a mobile-first casino, winning awards for its app. Now owned by MGM Resorts, it offers a large library of slots and live casino games alongside a sportsbook.
10. Bwin
Bwin, owned by Entain, is one of Europe’s longest-standing online sportsbooks, with a strong presence in markets such as Germany, Austria and Belgium. It is known for football coverage and long-running sports sponsorships.
How to Choose
Check the licence first, then compare odds, payment options, withdrawal speeds and the responsible gambling tools on offer. Be wary of unlicensed offshore sites promising huge bonuses. Regulation is tightening across Europe, and new markets are opening further afield, as the debate over gambling in the UAE shows.
The Bottom Line
Europe’s online gambling market is dominated by a handful of large, well-regulated groups, including Flutter, Entain, Evoke and Kindred. The best platforms combine competitive odds with strong safety tools. Gamble only what you can afford to lose, and if gambling stops being fun, use the support available, such as GamCare in the UK. 18+. Please gamble responsibly.
