The Simpsons Tapped Out, starts out with Homer accidentally destroying Springfield in a nuclear meltdown. You, the player are tasked with rebuilding Springfield and finding all the people who once lived there.
You will be given quests to rebuild each house, restaurant and store that you know from the show. Every time you finish a building you will get the character that goes with it (e.g. Kwik-E-Mart will give you Apu). If you tap on a character you will be given a list of tasks they can do. The tasks can take a few seconds or last a few days. Once they have finished their task, you will receive in game rewards.
Like most of these games, you are given timers for pretty much everything you do, with the option to buy stuff with real money. In this app, you can buy donuts, to either speed timers or purchase buildings and decorations. You will get donuts by leveling, but it is slow, and the prices for the stuff sold for donuts isn’t cheap.
This game has kept me hooked since I started playing a few months ago. They update with seasons and Holidays and you get new quests all the time. It’s definitely worth trying, especially since it’s free.
