Hustler - Winning $50000 by gambling
Fast Cash - Getting $100000 by day 10

When creating your character you can really be pretty flexible but theres are a few suggestions i have:

1) (Optional) Put 25 into charisma so you can start with pizza delivery job

2) (Optional) Get the perk "Wall Street Wizard" as this will help you in the long run by increasing your intrest rate

Step 1: Get a job, any job at all. i suggest the pizza delivery job as it can make you alot of money fast (it can also bankrupt you earlygame so be careful) Once you have at the very least £155 proceed to step 2.

Step 2: Wait until it is nighttime (10pm and onward) by wasting time any way you like though i suggest working as it make this whole thing easier.

step 3: Go to dimension 3 and speak to the red headed guy outside the store, buy a fake ID off him for $150

Step 4: go to the casino in dimension 3 and play the unicorn race game, Make sure you bet on the Blue Unicorn as he win the majority of the time and pays 3:2 so for every 5k you get 7.5k back ontop. (Keep in mind one horn wonder pays more than 9:4 so if you're feeling lucky at all he may be a good choice)

Step 5: Repeat step 4 untill you have the desired ammount of money you want!

If you have the Directors cut version (If you bought the game on steam you have this version) you are able to get a Benjamin Club membership card for $50000 at the Dandling Pianist in dimension 4.

At the Benjamin club you can play Unicorn races at much higher stakes but be warned i feel as if theres a much higher chance of losing from my personal experience that is even though the odds stay the same.
