Prize system

The prize system is a type of reward system in The Simpsons: Tapped Out. It was first seen in the Whacking Day Event, when the player had to collect snakes in order to win prizes. It was unique to other aspects of the game, as the balance of currency (e.g. snakes or GOO) accumulated and could not decrease. For example, prizes were staggered on milestones with a top prize awarded when the player collects a certain amount.

Personal prizes
Personal prizes were introduced with all three releases of the prize system, and rely on the player collecting points for their indipendant currency.

Whacking Day
In the Whacking Day Event, the prize system made its first appearance. The player must have collected snakes in order to win prizes. Snakes could be collected by whacking snakes in whacking mode. The top prize available in this event was the Sleep Eazy Motel with Miss Springfield, which was received after collecting 12500 snakes.

Treehouse of Horror XXIV
The prize system returned after 5 months with the second Treehouse of Horror event. This time, GOO replaced snakes as the currency. The top prize was the Gingerbread House with Suzanne the Witch, and was received when 10000 GOO was collected.

Christmas 2013
Most recently, the prize system was included in the Christmas 2013 Event, released in December 2013. For this event, gift cards must be collected by the player in order to earn rewards, the top prize needing 30000 gift cards to be collected. Gift cards are collected much more easily in higher amounts in this event, which is probably why the top prize requires three times more than what the Treehouse of Hoor XXIV Event did in GOO. The top prize was Costington's, a large retail shop. Mr. Costington is also unlocked upon completion of the building.

Community prizes
Community prizes were included in the prize system since the Treehouse of Horror XXIV Event. They work by adding together all Tapped Out players' currency or stats (depending on the event) and create a community total. The whole Tapped Out community have their stats put into one scoring system, and as the community total accumulates, more prizes are unlocked. In the Treehouse of Horror XXIV Event, the same currency (GOO) was collected for both the personal and community prizes. However, in the Christmas 2013 Event Gift cards were collected for personal prizes but community prizes were unlocked depending on how many gifts had been dropped in friends' towns across all players.
