We're going to be taking a look at how you can finish all of these tasks and eventually get a check by all the achievements in Billie ! A lot of the achievements in Billie are pretty self-explanatory, but some of them will require you to jump through some hoops to get.
The social media part of Billie just requires luck and determination. Just focus on something like YouTube or TikTok and post a bunch every year.
To reach the highest age, you really just need to make sure to keep your health stat as high as you can throughout the years. To complete the legacy achievements, you will need to pass your life to transfer over to your children.
Do some drugs at the club, drink alcohol every chance you get, and go gambling to get the three addictions. You can watch YouTube with friends, so just look for the Bijou Mike as an option.
Whenever you seek out a Sperm Donor, the person you are suggested to use will have a job listed. Purely random, you will just need to father or mother a lot of children and hope you get some triplets.
You can either marry a lot of old men, or you can help your husbands along to the grave by using the murder option. Going AWOL is a bit weird, but you have to get addicted to alcohol, go to rehab, and you will eventually get discharged.
Go get some plastic surgery done and pick the doctor with the worst rating. You will need to be born in Afghanistan and you can join a goat grabbing team once you start secondary school.
If the surgery is botched, you can use the Lawsuit option under Activities to sue the doctor. You get an heirloom each day, so look for the grail and make sure to play with it to complete the achievement.
Do not change the time on your device, it looks like Billie can detect this and you will get run over by a train! You will need to adopt an exotic pet with a high craziness stat and hope they murder your significant other.
Keep your health up by going to the gym, meditating, taking walks, and going to the doctor when you're sick. I also recommend living in countries that don't have estate tax such as Germany, Sweden, Switzerland (thanks u/Guillermo-Jubera) , Monaco, & Norway.
While there are other high paying jobs such as porn star, model, and music composer, I do not recommend these because you won't be able to make much extra money on the side. For porn star and model, you can do photo shoots, but they don't pay nearly as much as commercials do.
For flipping houses, buy equestrian properties & keep renovating them when necessary. Major in computer science and get a job as an app tester with Billie.
