I finished quite low on the leaderboard. When my sim, Erik, had used up all the ingredients that come with a fridge by default, he started eating the quick meals. He played logic for the majority of his spare time, in his house that, in retrospect, was too big.

I bought cheaply where possible - the lowest quality things except for a bed and shower. I got the expensive Base Game shower, and the Chinese-themed bed.
I got the Profession Simolean Booster LTR, mainly to help with earning money. I got another LTR, but I can't remember it at this moment. Everything fell apart in the last two workdays - Erik didn't get any jobs to capture spirits. I used the Scanner to scan for spirits, but he only reached Level 9, so I could not get him the Positioning Device. He got engaged and invited his girlfriend over for some woohoo when nessecary, and eventually had a child out of wedlock. The baby grew to a toddler, and when the challenge was over, Erik's son and his fiance moved in.
I used my free bingo's for the rarer ones - Evil Ancient, Lost Ancient, Jealous Ancient - and I was 1 away from a Ancient Bingo!
EDIT: Congratulations Largo! *pops champagne*
