Online casino products were the star performer in Denmark’s regulated online gambling market in 2016, according to new year-end statistics.

Figures released Monday by the Spillemyndigheden regulatory agency show sports betting and online gambling revenue rising 13% year-on-year to DKK 3.74b (US $533.3m) in 2016. For the three months ending December 31, the figure was up 7% to DKK 960m.

Overall sports betting rose 8.8% to DKK 2.17b in 2016 despite flat Q4 figures. Online betting accounted for DKK 1.4b of 2016’s total, representing slightly less than two-thirds of all sports wagering, in keeping with recent trends.

The biggest year-on-year gainer was online casino, which shot up nearly 24% to DKK 1.41b. The gains came primarily from online slots play, which rose to 72% of online casino revenue from 68% at the start of 2016.
