49.  100 Baby Challenge

The goal of this challenge is straightforward: you must have 100 children in as few generations as possible! Cheating is not permitted. 

The babies cannot be aged immediately, and females must become pregnant naturally. This is a thrilling, fast-paced challenge.

You begin with a single sim with very little money and assets in this challenge. The goal is to see if you can play the same family without cheating for 10 generations! 

To play, make a sim and place it on a 10,000 lot. This sim must amass a fortune and a family in order to pass on to the next generation, and you must do so for as long as possible. Congratulations after ten generations! 

 

47.  The Homeless Challenge

This is an extremely difficult one, so if you're looking for a true challenge, try the Homeless Challenge! 

Your sim will begin with no money and no home and will have to work their way out of homelessness. The catch is that you must live off the land with no job or home! 

Amass §5000 and construct a house to win - this can be accomplished by busking or collecting items.

 

46.  Build a City Challenge

This is a difficult task that requires commitment! The ultimate goal is to reach 50,000 points and control all of the households in your world by expanding your sim base and opening more lots.

Giving them opposing personalities or even randomising them makes this even more entertaining!

29.  Berry Challenge

Every generation in this colourful take on the Legacy Challenge represents a different colour and personality. Your sim's hair, clothing, skin colour, make-up, and décor all reflect the colour they have chosen. 

Each generation and race has its own set of personality traits and objectives to achieve. The Not So Berry Challenge, which does not involve changing your skin colour, is an option. If you don't want your Sims to be bright pink or blue, this version of the challenge may be more appealing.
