That means playing the game probably isn't going to get your kids through college. You have a certain amount of 'energy' which is consumed whenever you perform actions in the game (in this case renting extravagant homes, throwing wild parties, making dodgy investments, etc.) When you run out of energy, you have to wait for it to recharge, or pay real money for more. The basic mechanics of the game - and thus its revenue model - are pretty similar to just about everything else you see on Facebook. The object of the game is to blow through this money as quickly as possible and end up with nothing. This incentive program fits in neatly with the game's unusual premise: you assume the role of someone who has just inherited $300 million dollars. Specifically, Apps Genius says that the top 20% most active players each day will receive virtual rewards that can be turned in for cash worth 50% of the game's revenue that day.
