How to redeem codes

To redeem codes in Become a Deep Sea Explorer, look for the Codes button within the in-game menu. Enter your code exactly as shown and confirm to receive your reward. Codes are case-sensitive and single-use per account.

Codes reward Money (the primary currency for upgrades and aquarium expansion) and Mythical Fish - the highest rarity tier, normally requiring significant diving effort to find. The HLW33N code gives a Mythical Fish directly, and the HARPOON code gives 5,000 Money. Getting a Mythical Fish from a code is a significant head start, as it both generates high passive income in your aquarium and counts toward the Fish Index. The single-letter X code may be a developer event or social media exclusive.

The game has released codes tied to seasonal events (HLW33N is a Halloween reference) and pirate-themed milestones (HARPOON fits the game's aesthetic). Code activity is modest - 3-4 total - with releases appearing tied to updates and seasonal content. RIVRS Games does not have a confirmed public Twitter/X presence, so the developer's Roblox group and community Discord are the best places to watch for new codes.
