Supercell Raised $130M, Made $179M Last Quarter

"Most game studios have an autocratic executive producer green-lighting the work of designers and programmers. Supercell’s developers work in autonomous groups of five to seven people. Each cell comes up with its own game ideas. They run their ideas by Paananen (he can’t remember ever nixing a proposal), then develop those into a game. If the team likes it, the rest of the employees get to play. If they like it, the game gets tested in Canada‘s iTunes App store. If it’s a hit there it will be deemed ready for global release. This staged approach has killed off four games so far, with each dead project a cause for celebration. Employees crack open champagne to toast their failure. “We really want to celebrate maybe not the failure itself but the learning that comes out of the failure,” says Paananen."

The rest of the head count are these cells with failed launches.
