To really thrive in Roblox Restaurant Tycoon 3, you need to do more than just set up your restaurant and serve customers. It takes careful planning to make money, improve your business, and keep people happy, and using codes can make things a lot easier.
You’ll primarily succeed by taking care of customers, making money, and then using those earnings to improve your restaurant – things like the design, atmosphere, and hiring better staff. Codes in the game often give you Diamonds or Cash, which are really helpful when you’re trying to save up for upgrades or experiment with different restaurant designs. Here’s a list of the codes that are currently working, along with instructions on how to use them.

What are Restaurant Tycoon 3 codes used for?
Restaurant Tycoon 3 has codes you can redeem for in-game money and gems. Cash helps with everyday tasks like expanding your restaurant and making it run more efficiently, while gems are for special, more advanced features.
Diamonds allow you to upgrade your chefs past Level 3, decorate your restaurant with items from the EKEA shop, get fun hats and accessories for your staff, and buy music to boost your restaurant’s appeal and create a better vibe.
Where to find more codes
New codes for Restaurant Tycoon 3 aren’t released on a set schedule. You can usually find them announced on official Roblox channels, in the game’s update notes, or on the game’s Discord server. Because codes pop up randomly, it’s a good idea to save this page so you don’t miss any!
If you like playing Roblox games where you manage things, you should also look for codes and guides for Greenville, Neighbors, and Jupiter Florida.
