How to redeem codes

To redeem codes in Mermaid Isle, open the Codes menu from the main game UI, type or paste your code exactly as written, and submit. Codes are case-sensitive and single-use per account, so enter them carefully.

Mermaid Isle codes are among the most rewarding in the mermaid genre - they give Pearls (up to 3,333 from a single code), exclusive tail sets tied to seasonal events, and rare cosmetic accessories like Dragon morphs from the Season of Myths update. Pearl rewards directly fund tail unlocks, making each code a meaningful shortcut toward rare and Mythic-tier cosmetics.

New codes release with each seasonal update and major content drop - the developer consistently pairs major updates with a code as a community celebration. The Mermaid Isle Discord server is the first place codes are announced, with the Fandom wiki also maintaining an up-to-date codes list. Given the seasonal nature of the game's updates, codes tied to past events expire when the next season launches.
