China's biggest gaming and social network company Tencent Holdings said on Tuesday it will buy most of Finnish mobile gaming firm Supercell from SoftBank Group Corp and other shareholders in a deal valued at roughly $8.6 billion.

Tencent will, over three installments, acquire about 84.3 percent of Supercell -- the maker of the popular “Clash of Clans” mobile game -- via a wholly owned consortium, including all of SoftBank's 72.2 percent stake, the Chinese company said.

That consortium will then be open to unidentified co-investors, though Tencent expects to maintain a 50 percent voting interest, the firm said.

Supercell's current management will keep their operational independence and the company will remain in Finland, Tencent's statement said.
