You start the game with one penny, you have to find the person who is interested in trading your penny for anything more valuable then the penny for example a Pen, then sell the pen for a Coin, then buy a water bottle with that and sell it double the price, continue the cycle until you have enough money to afford the plane ticket to the next city,
You also have side quests like walking the Dog, collecting plastic trash and selling it, finding golf balls and starting a bid and food deliveries, Once you buy or rent any of the vehicle, You start getting food delivery orders. Use all the money to buy the plan tickets and reach to the mrBest and deliver him the penny but don’t waste your time since you only have 30 days, and remember to feed Trayan every day. Good Luck :)
