Restaurant Tycoon 3 Codes (Active and Expired)
Last checked August 3, 2026 (UTC)
Ultraw pushes Restaurant Tycoon 3 codes out at a pace most Roblox devs never match, sometimes several in a single week, so this list moves fast. I checked every entry against Try Hard Guides and Beebom today, and vivaldi is the newest drop.
Restaurant Tycoon 3 codes are the short strings Ultraw releases alongside updates and social posts, and they pay straight into your restaurant funds for free Cash and Diamonds, the two currencies that everything in your restaurant runs on. Cash covers the everyday build out, tables, decor, kitchen equipment and floor expansions, while Diamonds are the premium currency you save for the fancier unlocks. Early on, a few hundred free Cash is the difference between a cramped one room diner and a place with an actual kitchen line, and the Diamond codes spare you from grinding for the premium stuff.
Quick tip. redeem the whole list the moment you start a new restaurant, before you spend anything. Ultraw retires codes quickly to make room for new ones, and a code that pays 250 Cash today can be dead by the weekend. Stack the currency first, then plan the build.
Active Restaurant Tycoon 3 codes (3)
All of these worked when I last verified the list, and together they add up to well over two thousand Cash plus a healthy stack of Diamonds. Run through the whole batch in one sitting, since Ultraw prunes old codes without warning.
| Code | Reward |
|---|---|
| alora New Expires soon | 1.1x cash multiplier for 10 minutes |
| fishyfriday Expires soon | One-hour free trial of premium |
| auto123 Expires soon | One-hour free trial of auto money collection |
If a code comes back invalid, it most likely just rotated out, which happens weekly with this game. Trackers occasionally disagree on which codes are still live for exactly that reason, so I only list the ones multiple sources confirm.
Expired Restaurant Tycoon 3 codes
These had their run and closed, mostly update codes that got replaced by the next wave and a few launch era ones like RT3 and EarlyBird. Skip them, they return invalid every time.

Fresh Restaurant Tycoon 3 codes arrive with content updates and random social drops, often named after whatever the update added, like tiki7 for the tiki content or frosting2 for the bakery gear. There is no fixed schedule, just a dev who genuinely likes handing out codes. Redemption sits inside the Shop menu in game, no level requirement. One use per account, and the older codes rotate out fast once newer ones land, so the expired list below keeps growing.
- Redeem in game: Shop button at the bottom of the screen, then scroll to the Codes box.
- Codes pay Cash or Diamonds, nothing cosmetic to sort through.
- Ultraw drops new codes often and retires old ones just as fast.
- One use per account, so redeem everything on the account you actually play.
- vivaldi is the newest code, worth 400 Cash while it lasts.
How to redeem Restaurant Tycoon 3 codes
Redemption lives inside the Shop menu, which is slightly hidden if you have never looked for it, but takes ten seconds once you know the path.
- Launch Restaurant Tycoon 3 on Roblox and load into your restaurant.
- Click the Shop basket button at the bottom of the screen.
- Scroll down inside the Shop until you reach the Codes box.
- Type or paste a code into the text field.
- Hit Submit. The Cash or Diamonds land on your balance instantly.
If you are brand new, finish the short restaurant setup first, since the Shop button only appears once you are actually running your place.
Restaurant Tycoon 3 codes FAQ
What do Restaurant Tycoon 3 codes give you?
Cash and Diamonds, the two currencies the whole game runs on. Cash handles furniture, kitchen gear and expansions, while Diamonds cover the premium unlocks. No cosmetic filler, every code on the list is straight currency.
Why is my code invalid?
Ultraw rotates codes faster than almost any Roblox developer, so the most likely answer is that it simply expired. Double check the spelling with the Copy button first, and if it still fails, the code is gone and a newer one has probably replaced it.
How often do new codes come out?
Roughly every week or two, sometimes faster around updates. Ultraw has a long habit of shipping a small code with each content drop, which is why the active list stays this long while individual codes die quickly.
Do Restaurant Tycoon 2 codes work in Restaurant Tycoon 3?
No, the two games have separate code systems and separate economies. If you still play the older game, its own list is linked below, but nothing carries over in either direction.
What should I spend the free Diamonds on?
Hold them until something you actually want shows up in the premium catalog, since Diamonds are much slower to earn than Cash. Early game Cash problems solve themselves once your restaurant gets busy, but Diamonds stay scarce.
Where do new codes get announced?
Ultraw posts them on the game's social channels and Discord, usually alongside update notes. Trackers like Beebom and Try Hard Guides mirror them within a day, and I sweep those sources on every pass here.
