Mermaid Isle Beginner’s Guide: How To Play

You can download Mermaid Isle via the official Roblox app. When you first load into the game, you can explore all the underwater areas and earn resources.

Pearls are available from quests, exploration, and redeem codes. Most quests in the game are simple fetch missions where you have to pick up and deliver items. Once you have enough Pearls, you can head to Tuxedosam’s shop and buy cosmetics. There is no fixed progression system, and you can play at your own pace.
