Mermaid Isle Codes (August 2026)

Mermaid Isle is a Roblox experience built around collecting mermaid tails, accessories, and Pearls, the game’s main currency. Codes are the fastest way to pad out your Pearl count or unlock a tail you’d otherwise have to grind for, and the developer drops new ones fairly often as the game gets updated.

How to redeem codes in Mermaid Isle

You don’t need to hit a certain level or dig through hidden menus to claim a code here. The whole process happens through the Settings panel and takes just a few taps once your mermaid loads in.

Launch Mermaid Isle on Roblox and wait for your mermaid to load into the open sea.

Open the Settings menu from the main screen, or tap the cogwheel icon in the top corner of your screen.

Scroll down to the “Enter Code” box near the bottom of the Settings panel and type in your code exactly as it’s written, capital letters and all.

Tap Redeem. You’ll know it worked when your Pearl total updates instantly at the top of the screen, or when the new tail or accessory shows up right away in your inventory.

How to get more Mermaid Isle codes

New codes tend to show up around milestones like visit counts, holidays, and content updates, so it’s worth checking back after any of those. Your best bet for catching them early is the game’s own Discord server, where the developer posts codes as soon as they go live. The Roblox community page for Mermaid Isle is another place announcements land, and you can jump straight into the Mermaid Isle experience on Roblox to redeem anything new the moment you spot it.

Are Mermaid Isle codes free?

Yes. Every code above is free to redeem and only costs you the time it takes to type it into the Enter Code box.

Why won’t my code redeem?

A code that’s already expired, or one typed with the wrong capitalization, won’t go through. Copy it exactly as shown, capital letters included, and make sure it’s still on the working list before you try again.

Keep this page bookmarked if you play Mermaid Isle regularly. Pearls and tails don’t come cheap through normal grinding, so a working code is basically a shortcut to whatever you’re saving up for.
