How to start
- Create a young adult matriarch who can get pregnant; any traits, aspiration and looks.
- The in-game personality quiz may be used to set her up, but it is optional.
- Move her to any lot she can afford with her starting funds.
- Aging is on and lifespan is Normal; NPC auto-aging is recommended.
The rules
- Every child must have a different father; a donor can never be used twice.
- Donors give nothing: no moving in, no childcare, no money.
- The matriarch can't marry while she can still have children.
- No cheats except moving objects for building and fixing glitches; no mods that give an advantage.
- Kids may age up early only after milestones: infants after trying the baby foods, toddlers after level 3 in all toddler skills, children and teens after an A grade.
- An infant aging up with the Unhappy Infant trait fails the challenge.
- Children's traits come from the in-game randomizer.
- No nanny; maids, gardeners and repair people are allowed.
- Young adults may move out but never move back in; you can't remove underage kids to make room.
- The matriarch may only work from home or be self-employed; teens may have part-time jobs.
- Don't influence baby gender (no strawberries, carrots, pop or alternative music).
- When the matriarch becomes an elder, her youngest daughter becomes the next matriarch.
- Optional occult rules: occult babies born to a human matriarch count as two, or play an occult matriarch whose human babies don't count.
How you win
The 100th baby is born. Fewer generations is better. Breaking a rule fails the challenge.
Scoring
- Count the babies born (the 100th ends the run); the fewer generations needed, the better.
- Optional occult rule: each occult child of a human matriarch counts as two.
Tips
- Keep a stock of birthday cakes with candles placed, since each early age-up uses one and Sims won't snack on a cake that has candles on it.
- Add an NPC-heavy world (or turn on auto-aging for NPCs) so new adult donors keep appearing; you will run out of eligible townies fast.
- Make the youngest daughter the focus near the end of each matriarch's life, since she must be a young adult before the elder can move out.
