As of today, the management game I Simpson Springfield also lands on Google Play. Here's a trick to get 10 donuts without buying them, these tricks unfortunately work only once so you can't reuse it once you've used it. Here's how to proceed:
INFINITE CHAMBELS: During the course of the game, wait until Homer is not taking any action. At this point, click on his character by making the list of possible activities appear, and click 10 times on his head. As if by some miracle, 10 free doughnuts and a statue will appear to decorate the city of Springfield!
