  "textContent": "FISH.OS is an idle fishing simulator where progression revolves around catching fish, selling them on a dynamic market, and reinvesting profits into upgrades. Codes provide a direct way to obtain Black Pearls, a key currency used to accelerate upgrades and progression.\n\n### Working FISH.OS codes\n\n  * `missingfish` — 50 Black Pearls\n  * `D1SC0RD` — 50 Black Pearls\n  * `WH00PS` — 1,000 Black Pearls\n\n\n\n* * *\n\n### How to redeem codes in FISH.OS\n\n**Step 1:** Launch FISH.OS on Roblox and wait for the main desktop-style interface to load.\n\n**Step 2:** Select the Updates bell icon on the left side of the screen to open the code entry window.\n\n**Step 3:** Switch to the Enter Code tab in the pop-up window.\n\n**Step 4:** Input a valid code and press Redeem to claim the reward instantly.\n\n* * *\n\n### What codes do in FISH.OS\n\nCodes grant Black Pearls, which are used to unlock upgrades and improve efficiency. These upgrades can increase fishing speed, automate catching, and expand progression systems such as deeper water exploration and higher-value catches.\n\nThe game blends active clicking with idle systems, allowing you to accumulate fish over time and sell them strategically on a fluctuating market. Pearls obtained from codes reduce the time needed to reach stronger gear and higher-tier content.\n\n* * *\n\n### When new FISH.OS codes are released\n\nNew codes typically appear alongside game updates, milestone events, or community-related announcements. Since the game is in Beta and receives frequent changes, new rewards can be introduced without a fixed schedule.\n\nChecking regularly ensures you do not miss time-limited rewards tied to new features, balance changes, or special events.",
