Run Rich 3D is a three-dimensional runner that tasks a player with exploring adulting and making important life decisions. The player must direct their avatar through benefits and around obstacles on a white runway floating on an ocean. Their ultimate goal is to make their avatar as rich as possible by the end of the run.
The player can start their road to riches by claiming daily and spin wheel rewards. They can use the money to perform upgrades before the run that help increase the amount of money they make from their actions.
Once the player starts the run, they collect green stacks of cash and make positive or negative decisions. Positive decisions, such as going to school, studying, saving money and using employment-rather-than-social networks, appear as green gates. Negative decisions, such as partying, drinking, gambling, playing video games, grabbing red bags of stolen money and paying bills late, appear as red gates or red and purple objects. If the player isn't cautious and runs their avatar into a burglar, they also lose wealth.
Run Rich 3D can turn the player's avatar into a millionaire or a hobo. The outcome depends entirely on their decisions. If they perform well, they receive cash and luxury gift prizes and the opportunity to increase their winnings with a multiplier.
