The “Online gaming activity in Portugal” report for the last quarter of 2017 also showed that 17,600 players had self-excluded themselves from gambling, 4,600 more than in the third quarter of the year.
Odds betting, where the player bets against the operator, was worth about €68.1 million last year, the report said.
At the end of last year, 61.3 percent of gamblers were aged between 35 and 44, followed by 25 to 34-year-olds (39.3 percent) and 18 to 24-year-olds (27.8 percent).
More than half of the gamblers live in or around Porto (22 percent), Lisbon (19.5 percent) and Braga (9.7 percent).
Online gambling was legalised in Portugal on 28 June 2015 and the first licence was issued on 25 May 2016.
