France’s regulated online gambling market experienced its single largest year-on-year gain in sports betting and the highest quarterly wagering total yet recorded.

According to figures released Monday by French regulator ARJEL, online sports betting handle in the three months ending March 31 reached €516m, up a whopping 47% from the same period last year. Total online sports revenue by French-licensed operators improved by 30% to €82m.

ARJEL credited the sports betting gains to a 2.1-point rise in betting returns to players, which the regulator believes encouraged punters to reinvest their winnings, as did a 75% year-on-year increase in bonus offers. The numbers were also given a jolt courtesy of a 34% rise in the number of weekly active betting accounts.

Every single individual sport enjoyed solid gains in Q1, with football stakes rising 45%, tennis up 46%, basketball rising 57% and rugby gaining 71%, while hockey more than doubled year-on-year.
