The Sims/Money

Money in The Sims is known as simoleons, using the symbol "§". Simoleons can be earned by going to work, selling paintings, or from some phone calls you may get notifying you that you have won the lottery. Everything in the game costs simoleons; this includes buying new furniture, feeding your sims and paying taxes.
