10 Highest Grossing Free-to-Play Gaming Apps

Along with the bottomless pit of social media, YouTube, and obscure Google searches, online gaming is another activity that captures the imagination — and money — of smartphone users everywhere.

The particularly enticing 'free to play' market is, despite what you may expect, a massive money-making industry for smartphones, tablets, PC and Mac platforms. All it takes is one popular game to hook people in, encourage them to make in-game purchases, and make developers insanely wealthy overnight. For example, Blizzard's new and surprisingly popular online card game Hearthstone: Heroes of Warcraft is projected to generate $30 million in revenue in its first year alone. The developers of the game make their huge profits by offering the option to pay for extra card packs and passes for their “Arena Mode”. The high profits are nothing compared to other free-to-play games like League of Legends, that earned more than $600 million in 2013, but given how new it is, Hearthstone has proven a stunning success.

These PC and Mac games use an airtight business model to rake in high revenue despite being ostensibly free to play. They introduce upgrades, packages and other incentives that players can buy with real money. Gaming apps for Mac or Android devices take on the same model, some making millions every day. Here, we've gathered a list of the highest-grossing free to play gaming apps according to Think Gaming, and multiplied their daily revenue for an annual figure.

WARNING: If you already have a bone to pick with Kim Kardashian, you’re about hate her even more.
