Codes checked: 6 October 2026 · Game last updated by the developer: 5 October 2026
Looking for restaurant tycoon 3 codes? Twenty one are live, and the newest one landed with the delivery update Restaurant Tycoon 3 shipped on 5 October, which is the pattern here: a code goes out with the feature rather than on a schedule.
What makes this list worth reading in order is that it holds two different kinds of reward. Most pay a flat lump of Cash or Diamonds, but five pay a percentage boost on a timer, and those are worth nothing if you claim them and then close the game.
All Working Restaurant Tycoon 3 Codes

Five of those are timed boosts rather than currency, which makes the order you claim them in matter. Spend the Cash and Diamond codes whenever you like, and save the percentage boosts for a session you are actually going to play through.

How to Redeem Restaurant Tycoon 3 Codes
- Open Restaurant Tycoon 3 on Roblox and wait for your restaurant to load.
- Click the Shop button in the menu along the bottom of the screen.
- Type a code into the Type Code Here box exactly as written.
- Press Submit and the reward lands straight away.
Every live code is lower case, so copy rather than retype them. The box sits inside the Shop panel rather than on the main screen, which is the step people miss.
Cash, Diamonds and the Boosts Worth Saving
Cash is the building currency. It pays for tables, kitchen equipment and the expansions that seat more people, and the live codes hand over roughly two thousand of it between them, a real head start on a new save rather than pocket change.
Diamonds are the scarcer half and the live set carries forty. They buy what Cash will not, so there is an argument for sitting on them until you know what the game gates behind them.
The boosts need more thought. Four give twenty percent for ten minutes and one gives fifty percent for five, and a percentage of nothing is nothing. Claim them at the start of a run when the restaurant is already busy.
What Is Restaurant Tycoon 3?
Restaurant Tycoon 3 is a restaurant building game: you serve customers by hand at the start, cook the dishes they order, then reinvest the takings into a bigger kitchen and more seats until the place runs closer to itself than to you.
It is made by Ultraw and opened on 16 January 2025. As of 6 October 2026 it had 375.1 million visits and 901.7 thousand favorites, with about 6.1 thousand people playing at once, and the restaurant keeps earning while you are offline, which is the mechanic that keeps people coming back to it.
Where to Find New Restaurant Tycoon 3 Codes
Codes follow updates rather than the calendar, and the names give that away: the newest one is named after the delivery feature that shipped the same week. Watching what the game adds is a better predictor here than watching any date.
Announcements go out in the developer’s own community, the Ultraw Games Discord server, and the Roblox description points to a developer forum thread for the changelog rather than carrying a code list of its own.

Frequently Asked Questions
How many Restaurant Tycoon 3 codes are working right now?
Twenty one, as checked on 6 October 2026. The newest arrived with the delivery update of 5 October, and eighteen older codes have been retired.
Where do I enter codes in Restaurant Tycoon 3?
Behind the Shop button in the menu along the bottom of the screen. It opens a box labelled Type Code Here with a Submit button beneath it.
What do Restaurant Tycoon 3 codes give you?
Cash, Diamonds, or a timed percentage boost. Cash builds the restaurant, Diamonds are the scarcer currency, and the boosts only pay out while you are actually playing.
Why did my Restaurant Tycoon 3 code not work?
Usually capitalisation, since almost every live code is lower case and the game will not accept a retyped upper case version. If it still fails, the code has been retired and will be in the expired list above.
