The Sunsphere or sometimes known as the Wigsphere is the fourth and cheapest available to purchase in The Simpsons: Tapped Out, following the Escalator To Nowhere, Popsicle Stick Skyscraper and the 50ft Magnifying Glass. It is the only aspirational building to be priced at under 1 million cash, and was released in August 2013 along with the Level 33 update. The Sunsphere unlocks a quest involving Bart, Milhouse, Martin and Nelson. The player must be Level 5 in order to purchase it, however the quest won't start until Level 21.
