The Sims Twins Cheat: Does It Exist? (Vanilla Game vs Mods)

No official cheat forces twins. Twin chance is determined by:

• Genetics (hidden "twin token" from parents).
• Fertility Treatment lifetime reward (increases odds).
• Watching "Kids' TV" channel during pregnancy (small boost).
• Random roll at birth.

Using testingcheatsenabled true

• Shift-click Sim → "Trigger Age Transition" to speed pregnancy.
• Shift-click → "Modify Traits" to add Fertile trait (if modded).
• No direct "force twins" command exists in vanilla game.

Mods (e.g., NRaas MasterController) can force multiple births, but that's third-party.
