Online gaming grew by 6.6 percent in Europe during 2016 according to a report by U.K.-based research firm Eilers & Krejcik Gaming.
The report put the European online gaming industry at $19.3 billion for the year and pointed to an increase in regulated markets as a reason for the growth.
UK-based bet365 remained the biggest player in the market with about eight percent of the market share. Paddy Power Betfair controlled seven percent.
The growth happened despite uncertainties in markets like Poland, the Czech Republic and Portugal which have been revamping their regulations. Bet365, for example has just announced it is withdrawing from the Polish market.
