The rich get richer: Mobile heavyweights Candy Crush Saga, Clash of Clans reign worldwide

Maybe you just need to use a lot of words that start with the letter “C” if you want a huge mobile hit.

Candy Crush Saga is the most played iOS gaming app in the U.S. and U.K., but Clash of Clans tops the leaderboard in South Korea, reports Mobidia Technology Inc. Clash of Clans is second in the U.S. and U.K., while Candy Crush Saga is fifth in South Korea. The mobile market is huge, and these two games, which dominate the top charts in just about every region, are benefiting handsomely from it — and show how different sort of games do on a worldwide scale. Games make up 40 percent of all app-store downloads and about 75 percent of spending. Mobile games could hit $20 billion worldwide this year.
