The Sims 4: How to Do the Upgrowth Challenge

Rules for Setting Up Your Lot and Building Your Home

Recommended Videos

You are allowed to use money cheats to build your home as long as you adjust the money once the building process has been completed. If you don’t want to build a home, there are pre-made homes available to download from the gallery. All you’ll have to do is search the hashtag #UpgrowthChallengeBuild.

  • You can’t have any items that use electricity except for a refrigerator and stove. This means you’ll want to use candles, lanterns and large windows for lighting.
  • You are allowed (and recommended) to have a sewing machine, loom, notebook, and teapot.
  • You can have a bathtub but no shower.
  • Toilet must be placed outside to recreate an outhouse. Also, all CC plumbing that makes sense for the given decade can be used as well.
  • All furniture must be wooden or stone.
  • You are allowed to place debug fishing spots on the lot.
  • If you want to have a farm or garden you are allowed to start with plants already planted.

Rules for Lifespan and Time Progression

This is a pretty lengthy challenge so it’s highly recommended that players use the normal lifespan progression length or even opt for the short lifespan length. You will not be allowed to manually age up any of your Sims before their birthday so make sure you adjust the lifespan progression length to fit your personal level of patience.

There are two different ways to determine when you should advance to the next generation. The first option is to start a new generation whenever the first born child during the current generation reaches the Young Adult life stage. The other option is to track generations by days instead. In this scenario you will have less time to focus on building your family but it does create a more consistent gameplay experience. If you prefer this method, you will start a new generation every 20 years.

  • Short lifespan: New decade starts every 22 Sim days
  • Normal lifespan: New decade every 40 Sim days
  • Long lifespan: New decade every 156 Sim days
