Achieving success in Real Racing 3 without in-app purchases is possible, but it requires patience, skill, and strategy. Real Racing 3 is a racing simulation game that includes several in-game currencies, and it can be a significant challenge to earn enough credits and gold to purchase the best vehicles and upgrades without making any actual purchases. To beat the game without paying, players must focus on winning races, accomplishing achievements, playing daily events and competing in special events. It's important to also choose and upgrade the right vehicle for each race, manage the car's racing strategy, and keep a close eye on the in-game economy. While it may take longer to reach the ultimate goal of completing the game without using any real money, the sense of accomplishment from doing so can be a rewarding experience for dedicated players.
