Following the decision, the operator said its returning customers in the Swedish market are at an all-time-high.
Last month, LeoVegas, and its subsidiary Royal Panda, received fines totalling €750,000 after the Dutch Gambling Authority found both sites were accessible with a Dutch IP address.
Gustaf Hagman, President and CEO of LeoVegas, said: "We continued to show progress during the third quarter in a difficult-to-navigate environment and generated double-digit growth in both sales and operating profit.
"Greater regulatory complexity in several of our main markets has given rise to certain short-term challenges but is also raising the barriers to succeed in the sectors which benefit established companies.
"We continue our efforts to execute our strategy of innovation, expansion and profitability."
