There is no official notsoberrychallenge.com site; the rules live on lilsimsie's Tumblr. Rules differ between copied versions online, so the tables below follow the original sources. Each challenge name above opens its full rules page.
To compare every family format side by side, see the generational challenges list. If you own no packs, start with the base game challenges.
Legacy Challenge rules
Created by Pinstar and now run with Mystic. Current pages date from 2020 to 2023. The site announced a full rules overhaul in November 2024 and began a playtest series in February 2025; the published rules have not changed yet. Every law and score threshold is on the Legacy Challenge rules page.
- Start with one young adult founder on any empty lot and set funds to §1,800 with
money 1800. - 10 generations, Normal lifespan.
- No cheats or mods that give an advantage. Cosmetic CC is fine; MC Command Center is allowed only to raise the household size limit.
- Banned: money cheats (
motherlode,kaching), Potion of Immortality, Money Tree, the Lottery holiday, resurrection, and reloading after bad events. - Anti-aging and the Wishing Well: once per Sim. Spouses join with no money.
- Children's traits come from the Random Trait Generator, no rerolls.

100 Baby Challenge rules
Rules by Snarky Witch, who wrote the Sims 4 version and credits Amiisays with the Sims 2 original. Her rules page was last updated in February 2025. Age-up marks and pack rules are on the 100 Baby Challenge rules page.
- The matriarch starts as a young adult, alone, in any lot she can afford with her starting funds.
- She can't take a job that sends her off the lot (self-employment and work-from-home careers are allowed), and can't marry or move anyone in while she can still have children.
- Each donor can father only one pregnancy. Donors can't move in or help.
- Twins and triplets are allowed: the limit is one pregnancy per donor. Many copies online say otherwise.
- No cheats except moving objects (
bb.moveobjects on) and fixing glitches. - Banned mods: anything that gives an advantage, such as more than 8 Sims per household or child support payments.
- Normal lifespan, nothing that extends life or prevents death, and no nannies (maids, gardeners and repair techs are fine).
- Infants must age up Happy or Top-Notch. An infant who ages up Unhappy ends the run.
- When the matriarch becomes an elder, her youngest daughter takes over.
- Win: the 100th child is born. Breaking a rule ends the run.
Rags to Riches and Decades Challenge rules
Rags to Riches (SimishGamer, Mod The Sims)
- Move into the most expensive empty lot, then remove all money with
money 0. Only reset, money-removal and move-objects cheats are allowed. - Unlocks: building needs Handiness 5, Logic 3 and a §500 noise fine; a garden needs Handiness 7, Gardening 5 and §500; a job needs basic furnishings and §1,000 for a degree.
| Win condition | Requirement |
|---|---|
| Home | 3+ bedrooms, 2 bathrooms, a study with a computer, a garden and a pool |
| Family | Marry, then become a grandparent |
| Career | Level 10, or §100,000 from a business |
| Aspirations | One completed each for the founder, spouse and every child |
| Money | Home worth §100,000+ and §200,000+ in the bank |
"Sell the house and start with §1,000" versions are fan variants, not this ruleset. The Rags to Riches rules page has every unlock step.
Decades Challenge (CuteCoffeeGal's rules)
- Start in the 1890s and play through the 2010s, with a 2020s bonus round.
- Long lifespan with manual aging. Simple aging: 1 Sim day = 6 months, so one decade every 20 days. Complex aging (needs Discover University) takes 80 days per decade.
- Starter funds only; any cheated money is a loan repaid at 10% interest.
- No vampire, mermaid, spellcaster or werewolf gameplay, and no home in StrangerVille.
- Wars are simulated with a cow plant cake and a dice roll.
- Heirs are male-only in the 1890s; women can be heirs from the 1920s on.
The original idea is credited to ZombieCleo, with rules modified by kakeru_naruse. "Ultimate Decades" is a separate challenge by Morbid Gamer that starts in the 1300s. Both are covered decade by decade on the Decades Challenge rules page.
Tips for finishing a long challenge
- Write your laws down before generation 1: gender, bloodline and heir law for Legacy, or your own heir rule for Not So Berry, which sets none.
- Keep a backup save each generation, even in challenges that ban reloading. Corrupted saves are not "bad events".
- Use the Random Trait Generator openly when rules require it, so you can't be tempted to pick.
- Track points in a spreadsheet. Legacy categories like Food and Nature are easy to forget until generation 8.
- Check pack needs: several NSB generations use pack content (the Mint Scientist career and the Yellow generation's trip to Sixam come from Get to Work). In the Decades Challenge, complex aging needs Discover University. The base game challenges list shows what you can play with no packs.
Not in the mood for ten generations? See the Black Widow Challenge for a different kind of story, or the build challenges if you would rather build than play a family.
Challenge-style play in a real city
Most challenges are about one thing: living a life under limits and seeing what story comes out. LifeSim is a free life simulator that runs in the browser on a computer or phone, with no download and no packs. You can be anyone in any real city on Earth and live a life day by day, with needs, a job, relationships and AI-driven townspeople, so you can set your own rules: start with nothing, chase one career, or raise a family.
