In reality, these free casino slots are anything but. But there’s one big problem: Players can’t win real money, they can only spend real money. Free slot games – slot machine apps for iPhone, iPad, Android, and Facebook – pull in tens of millions of dollars per day in the US alone. Free slots are the most popular video games in the world, and the mobile slot apps you find on the App Store, Google Play, and Facebook are the highest-grossing titles on these platforms.
