Free donuts are available during various stages of the game. A few are given to players when starting the game, as well as when getting to the first level, and while cleaning up Springfield during the beginning of the game. They are also available from Mystery Prize boxes.
Donuts can also be purchased with real money for players who need more of them but are not able to find them for free. The available purchases for donuts range from 12 donuts for $1.99 to 2,400 donuts for $99.99. Donuts are also converted into cash within the game, such as trading in five donuts for $500 in-game cash or getting $5,000 in in-game cash for trading in 41 donuts.
