The operator said the period marked its sixth year of consecutive growth, and that revenue grew more than 1.5 times more than the social casino market average of 24.4%.
During the period, it said, the mobile gaming market in general grew by 18%.
The operator celebrated 10 years in business, and saw its number of unique players surpass 150m in 2020.
KamaGames’ flagship title, Pokerist, remained the third largest social poker game globally, and was the leader in 12 countries. The game also rose to become the largest poker app by revenue on iOS in Spain, the operator said.
Its second largest product, Blackjackist, grew by more than 40% in revenue, more than half of which came from customers in the US. Blackjackist is currently the global leader among social blackjack games, KamaGames said.
Its Roulettist game also remained the largest social roulette game in the world throughout the period, and saw revenue growth of 70%.
The operator said a number of factors contributed to its success in 2020, including the cultivation of key partnerships, such as the launch of the Hard Rock Blackjack app in March.
KamaGames said other factors in its success included the launch of new poker and blackjack tournaments, the introduction of VIP benefits for some of its paying customers, a renewed focus on advertising monetisation and an emphasis on CRM and gaming activities.
In April, the operator revealed it had recorded record gross revenue of $29.3m (£23.7m/€27.0m) in the first quarter of 2020.
2019 saw the operator bring in $90.4m in revenue, with year-on-year growth recorded for each month of the year.
