Restaurant Tycoon 3 Codes (August 2026)

Restaurant Tycoon 3 is the Roblox management game where you build up your own restaurant, hire staff, and serve customers to earn Cash and Diamonds. The developers hand out codes every so often that drop free Cash, Diamonds, and temporary boosts like Cash Multipliers or free trials of premium features straight into your account.

Working Restaurant Tycoon 3 codes

Here’s every code you can currently punch in for a reward. Type them in exactly as shown below, since Restaurant Tycoon 3 codes are case-sensitive.

Tip: Grab the Cash and Diamond codes first if you’re early in the game since they’ll help you unlock kitchen upgrades faster. Save the free trial codes like fishyfriday and auto123 for a session when you actually want to test out Premium Staff or Auto Money Collection, since the clock starts running the moment you redeem them.

How to redeem codes in Restaurant Tycoon 3

Codes in Restaurant Tycoon 3 don’t go through a dedicated codes button, they’re tucked inside the Shop menu. Here’s exactly where to look.

You’ll know a code worked when your Cash or Diamond total at the top of the screen jumps up right away, or when the trial timer for a perk like Premium Staff starts counting down. If nothing changes after you hit Submit, double-check your spelling and capitalization before trying again.

Expired Restaurant Tycoon 3 codes

These codes have stopped giving out rewards, so don’t waste your time typing them into the Shop menu.

How to get more Restaurant Tycoon 3 codes

New codes usually show up around updates, holidays, or milestone celebrations for the game. Your best bet for catching them early is joining the official Restaurant Tycoon 3 Discord server, where the developers post announcements directly. You can also keep an eye on the game’s page inside the Roblox app itself, since Restaurant Tycoon 3 often gets its description or thumbnail updated when a fresh batch of codes goes live. There’s no fixed schedule for when new codes drop, so checking back every so often is the safest habit.

Are Restaurant Tycoon 3 codes free?

Yes. Every code above comes from the developers themselves and doesn’t cost you anything to redeem, they simply add Cash, Diamonds, or a timed perk to your account once submitted through the Shop menu.

Why didn’t my code work?

The most common reason is a typo, since these codes are case-sensitive and even a single wrong letter will stop them from going through. If you’ve copied a code exactly as shown and it still won’t submit, it’s likely already expired and no longer active.

Keep this page bookmarked and check back before you plan a big kitchen upgrade, that way you can stack any fresh Cash or Diamond codes before spending on new equipment.
