“Gross winnings revenue increased 24% organically and in constant currencies which means that we are continuing to gain market share. Gross winnings revenue from mobile grew by 29% compared to the second quarter last year and amounted to 72% of our total gross winnings revenue. Of the group’s gross winnings revenue 43% came from locally regulated markets.”
