Here's how 'Clash of Clans' app makes $1.5 million a day

The mobile game Clash of Clans is free to download and free to play, so how does it pull in an unheard of $1.56 million revenue everyday? The secret to its status lies in how it has perfected the 'freemium' model.

For a mobile game, 'freemium' means the initial download is free but that certain virtual goods within the game's digital universe cost real cash. While some games force you to pay extra to access higher levels, Clash of Clans has implemented a subtle strategy.

Players in Clash of Clans collect resources that enable them to build defensive structures and troops. They can then use troops to attack other players' bases — in order to get more resources. You see? It's an endless cycle of building, protecting and stealing. And an inf lux of real-world money into the equation can speed up many aspects of the game.

Candy Crush's business model works in the same way, with users being able to pay real money to avoid waiting for more lives. But despite Candy Crush addiction being a well-known scientific fact, the game only makes $9,31,000 in one day.
