HELSINKI (AP) — The maker of the "Clash of Clans" mobile game, Supercell, says its pre-tax profit last year grew more than 60 percent to 838 million euros ($964m) while revenue surged a third to 2.1 billion euros.

CEO Ilkka Paananen said Wednesday they were proud of the success but acknowledged that "enough time and some luck" were needed to continue producing games that interest millions of people worldwide.

The Helsinki-based company, also known for "Hay Day" and "Boom Beach," this month released globally its fourth game, "Clash Royale," which last week was the top grossing iPhone game in 44 countries.

Supercell employs 180 people in five global offices. On Tuesday, it said it had reached 100 million daily active players of its four games.
