From the article, "The Simpsons: Tapped Out is very popular on both iOS and Android. The brand alone was enough to earn EA millions of dollars in revenue. EA made this kind of money by littering the game with in-app purchases. Donuts, which serve as premium currency, are integral to progressing in the game in a reasonable amount of time. Donuts decrease quest and build times, and they’re used to purchase the best items. Simply put, you won’t get your ideal Springfield without buying donuts. The problem is donuts can get expensive. 12 donuts costs $1.99, 60 donuts is $4.99 and 2400 donuts is $99.99. The way this game is set up, you’ll be burning through donuts (and your money) like crazy. This had led to an uprise in hacks. These hacks are especially popular for Android since they’re quite easy to implement. iOS devices can also use these hacks."
