Aging and Your Sims

Your Sims in TS3 have flexibility at your fingertips as far as aging goes. You can adjust the aging in your options bar to age quickly or as slowly as you please. TS3 gives you a little more flexibility on aging up a Sim. You are notified 2 days in advance at which time you can buy a Birthday Cake and have a small Family Party, or a larger Party Animal Party. As in TS2 upon blowing out the candles your Sim will age to the next age level. You can also right click the Birthday Cake and choose which Sim you would like to advance in age.


There are three ways to have a birthday (age up your Sim):


You can buy a birthday cake from the game menu:

  • Buy -> By Function -> Entertainment -> Parties

Any Sim can blow out the candles at any time - it doesn't even have to be their birthday. Once you let a Sim blow out the candles they will skip the rest of their current age and move on to the next instantly, so make sure you pick the right Sim!


If you want to just play and not worry about aging, this is the one for you. Everytime a Sim reach their natural birthday they will age up automatically. Remember you can control how quickly this happens with the Age Setting.


If you simply can't wait for your toddler to become a grown up and you're tired of ordering Cakes, it's time to cheat:

  • Press <CTRL-SHIFT-C> (or <CTRL-WINDOWS-SHIFT-C> in Vista) simultaneously to bring up the Cheat Console.
  • Type in testingcheatsenabled true.
  • Hold down <SHIFT> and click on the Sim you want to age up, then click "Trigger Age Transition".

Careful with cheats!

Once you've triggered the Age Transition cheat you can't cancel it. You can also only age Sims up - not back down again!
