Simoleon is a fictional currency used in many video games, most notably the Sims game series. It is commonly used in games as a virtual currency to purchase items, clothing, furniture, and other in-game assets. The term "simoleon" is believed to be a play on the word "simulacrum," which means a likeness or imitation of something.
