ISBI Challenge (Lynnwood)

TS4 adapted by Lynwood, official link…

Getting Started

Create a YA sim, give them whatever looks, traits and aspiration you’d like. One of the traits given to your founding Torch Holder MUST be Insane. They can be ‘human’ sims or aliens, your choice.

You will be playing on NORMAL lifespan.

Move your TH onto a lot. There is no restriction on which lot that can be. Build them a house, import a house from the gallery or let them live on the lawn for a while – whichever play-style you prefer is fine. This should be done with the standard 20,000 starting simoleons. Whatever you have left after purchasing property and house, that’s your starting funds.

Find a spouse/baby-maker (human or alien). This can be anyone your sim can manage to woo; townies, premades, even sims you’ve placed into the neighborhood yourself just for this purpose. They must be asked to move in or married IN-GAME however, not placed into the household via Manage Households. Other than that, everybody’s free game.

Once you’ve acquired your mate, have some kiddos. Adoption is fine, but they must be adopted as infants. I do this for sims and/or simmers who’d like to have same-sex couples.

Once you receive the notification that it is the sim’s birthday, you are then allowed to age them up via birthday cake.

The Goal

The ultimate goal is to survive 10 generations of sims while only controlling one sim at a time, and keeping score throughout.

Each Torch-Holder must have at least two children. You don’t HAVE to get married, but doing so increases the chance for more points (and more failures). If playing with the Insane trait rule then each child MUST be given the Insane trait at some point. Otherwise all traits and aspirations should be randomized.

Throughout the challenge, only ONE sim may be controlled by you, and that’s your current Torch Holder. All other sims must live on complete autonomy, to live (or fail) as they will. Obviously this means that sim autonomy should be turned on in your game settings at all times. When the child you’ve chosen as heir reaches YA, the ‘torch’ is passed to them and they become your controllable sim. Your former TH enters the land of autonomy and you are never allowed to control them again.

Once a child reaches YA and they are not your heir, they must be moved out of the household.

  • Every 100,000 simoleons earned : +20
  • Immortalizing the Torch-Holder : +5

Free Actions

Every sim in the household has one free action per age category.

The actions listed below are ALWAYS allowed to be done whenever and however many times you need to.

  • You may choose to “Claim” a bed with every sim ONCE to assign specific beds to specific sims. This can only be done once. After that, they’re on their own.
  • You may choose to quit job/retire for any sim you don’t want working, and are allowed to assign sims to specific careers as needed.
  • You may choose to “Change Into…” out of sleepwear, (because I get tired of seeing them in their underwear/PJs ALL DAY).
  • You may change tones while at work/school as needed. Whether or not they actually attend or leave early is up to the sims themselves.
  • You may choose to take vacation days or family leave for NTHs via the phone.
  • When you get the notification for infants that it’s their birthday, you are then allowed to select the bassinet (with your Torch Holder) to age them up. Also when all other sims’ age bars reach 0, you are allowed to click on a birthday cake to age them up. Baking the actual cake and adding candles is up to your TH however.
  • You may choose to take a Pregnancy Test with NTH female spouses to determine if there is a pregnancy. This CAN be discovered without the test with time, but I can see how the wait would be a little annoying since there are no chimes anymore to tell you yay or nay.
  • Once a NTH spouse goes into labor, you are allowed to choose to go to the hospital, and may then ‘Check-In’ at the front desk. All other actions at the hospital must be autonomous. If at home, you must wait for the labor to end naturally (the timer to run down on its own).
  • You are allowed to purchase and drink ONE youth elixir per sim, per lifetime. (HOWEVER, doing this with a NTH spare will negate the +10 points for not using AP in that generation).


If you’re interested in writing and/or reading sims stories, participating in fun competitions and events, joining a friendly and welcoming community, completing legacies and challenge and earning medals, or just having a great place to discuss Sims 2, Sims 3, or Sims 4, then there is a place for you at the Forums
