Estimated daily revenue from Candy Crush Saga: $632,867 King’s puzzle app has taken the world by storm, becoming the top-rated game in Australia, Germany, Singapore, and Sweden. But that’s just the beginning. Rumor has it King is preparing an IPO in the wake of Candy Crush Saga’s popularity, though the company has yet to publicly comment.

Estimated daily revenue from Clash of Clans: $527,389 The combat strategy game is popular in most countries, especially Russia and Switzlerland. The Finnish developer has over a million daily users and has partnered with GungHo Online for a campaign that aims to take on bigger developers. Supercell is valued at $770 million, according to Business Insider.

Estimated daily revenue from War of Heroes: $421,911 Japanese website provider DeNA teamed up with Marvel Entertainment for the card-based game featuring original art and stories. The games live on DeNA’s Mobage social games platform, home to hits like Blood Brothers and Rage of Bahamut.

Estimated daily revenue from Modern War: $361,789 With over 10 million users, Modern War’s fans could make up a small country. Of course, that’s part of the game’s appeal: players team up for missions in which they compete to take over the world. Japanese developer GREE has produced other combat games such as Knights & Dragons and Crime City and it’s one of Japan’s largest social networking services. Analysts attribute the company’s success to its track record of investing in developers.

Estimated daily revenue from Puzzle Dragons (English version): $41,173 Serbia’s Nordeus is one of Europe’s fastest growing developers. Its main game, Top Eleven, is a football simulation with over 11 million monthly users. Nordeus, which has branches in Belgrade and San Francisco, recently expanded to Dublin.
