The average paying user in the U.S. spends $32 a month playing Homescapes, Playrix’s most popular game, the company said.

While Playrix hasn’t introduced a new title since 2017, the company recently acquired several gaming studios to expand into new genres, Igor said, declining to disclose which studios until it releases games developed by them later this year.

Successful titles attract whales. Activision Blizzard acquired King Digital in 2015 for $5.9 billion, and a year later Tencent led investors in an  $8.6 billion deal to acquire a majority stake in “Clash of Clans” maker Supercell Oy.

Could Playrix be next? In February, the Information reported that it could be sold for $3 billion, citing Chinese firms iDreamSky Technology Holdings and FunPlus Game Co. as potential suitors.

The brothers dismissed the report.

“For $3 billion we won’t sell,” Dmitry said with a smile, while acknowledging that Playrix had been discussing strategic options as recently as last year, noting its meetings with Wall Street banks.

Their goal, for now, is to become a “top-tier gaming company,” that rivals Activision Blizzard and Electronic Arts in the West, and NetEase Inc. and Tencent in China, Igor said.

“We want to grow as big as they are, using developer talent from our region—the former USSR and Eastern Europe,” he said.

There’s no magic number that would compel the Bukhmans to sell the company, because they say money is secondary to doing what they love.

“Some may think that when you have a lot of money, everything becomes different and more interesting, you start doing different things,” Dmitry said. “But no. We just keep working.”
