Restaurant Tycoon 3 Codes FAQ
Codes for RT3 aren't case-sensitive, but you could've still made a spelling error if you were typing them out. So, double-check your spelling and make sure you haven't already redeemed that specific code.
Can You Redeem Codes Again if You Create a New Save?
No, you can't redeem already used codes if you create a new save. Each code can be redeemed only once on a single Roblox account.
Is Using Codes Necessary for Quick Progression?
