Fish It! Codes

✅ Last checked: 2026-09-30 — we verify these codes daily. Redeem them soon, codes can expire without warning.

Looking for Fish It codes that still work? This page tracks every code Fish Atelier has released for its fishing game on Roblox, tests each one, and keeps the list clean. There are 27 active codes right now and 9 that no longer work. The last full check was on 2026-09-30.

One rule matters before anything else: you must reach Level 10 before the game accepts any code. Fish for a while first, then come back. Most codes give Mutation II or Luck II Potions, a few give skins for your rod, lantern, or bait, and a handful are tied to specific places like Leviathan's Den, so read the reward column before you redeem.

We re-check the list regularly. When something stops working it moves to the expired section instead of disappearing, so you can see at a glance what is still worth typing in. Copy from the table below, then follow the redeem steps further down. And note this is not Fisch, a different fishing game whose codes will not work here.

Expired Fish It! Codes

POTIONSSS
FREEPRESENTS
CELEBRATE
HAPPY2026
SCALE2
FISHING
VALENTINE
INDO
BIGUPD

The codes above have been confirmed dead. Most were seasonal: HAPPY2026 and VALENTINE marked holidays, FREEPRESENTS and CELEBRATE came with event updates, and INDO was a regional celebration code. POTIONSSS and SCALE2 were short-lived reward drops, and FISHING and BIGUPD were early update codes the developer retired as the game grew.

Fish Atelier ships updates weekly, and each update tends to add a code or two while quietly retiring older ones, so the expired list here grows faster than in most games. The game does not tell you why a code failed, it just says invalid.

We move a code here the same day we confirm it fails, and we never delete it, because plenty of players still search for these names and deserve a clear answer. If an expired code somehow still works for you, let us know and we will re-test it.

How to Redeem Fish It! Codes

Launch Fish It! on Roblox and reach Level 10.
Look for the Settings or Codes button on the main screen.
Enter the code exactly as shown (codes are case-sensitive).
Press Redeem to claim your reward.

Where the code box is

Once you are Level 10, the code box is behind the Settings or Codes button on the main screen, in the row of icons around the edge of the HUD. Click it, find the code field, paste, and press Redeem. Before Level 10 the field either refuses input or returns an error no matter what you type, which is the single most common reason players think the codes are broken.

PC vs. mobile

On PC, click the field, press Ctrl+V (Cmd+V on Mac) to paste, then click Redeem. On phones and tablets the same button is in the HUD. Tap it, tap the field, hold until Paste appears, then tap Redeem. The layout is identical across platforms.

Codes are case-sensitive and a few contain underscores, like 1M_GOAL and 500K_GOAL_FXCB. Those underscores are part of the code, and COUNTTRANSCENDEDSTONES is long enough that a single missed letter is easy, so paste from our table.

Codes that need you somewhere specific

A few entries only work once you have done something in the game. THEDEN and LEVDEN expect you to have visited Leviathan's Den, and SCALEREFUND only pays out after you have completed the Leviathan quest, because it refunds the Leviathan Scale that quest consumes. COUNTTRANSCENDEDSTONES advances the Element Rod quest rather than giving an item. Redeem those after you reach the relevant area, not before.

What Do Fish It! Codes Give You?

Potions are the bulk of the rewards. Mutation II Potions raise the chance that your next catches come with a mutation, which is what makes a fish valuable, and Luck II Potions improve the odds of rare fish outright. Codes like CONTRA, MUTATION2, DIVING, PIRATEMAJA, and 3BILLION each give two, so redeem the full list and you have enough potions for a long session.

Skins are the second group. MERDEKA and NEWYEARLANTERN give lantern skins, GO2026 gives a rod skin, CRESCENT and PURPLEMOON give bait skins, and YEEHAW gives the Cowboy Hat Halo. None of them change your stats, but several were limited to an event and cannot be bought any more.

The rest are one-off items: Cave Crystals from FREECRYSTAL, Luck Totems from SORRYQUEST and LUCKYTOTEM, an Epic Present from GIFTGIVING, and a Leviathan Scale from LEVDEN. The Scale in particular is expensive to earn normally, so that code is worth more than it looks.

Where to Find New Fish It! Codes

Every real code comes from Fish Atelier, the studio behind the game. They announce new ones in the official Discord server, in the game description on Roblox, and in the notes that appear with each weekly update. Codes tend to arrive with milestones (1BILLION, 2BILLION, 3BILLION marked visit counts), regional and seasonal events (MERDEKA, EASTER2026), and new areas like Leviathan's Den.

You do not need to follow those channels yourself. We watch them and add anything new here, usually within a day of release.

Be careful with random videos or sites promising secret codes for legendary fish or free Coins. If it is not on the official channels it is not real, and anything asking you to log in or install something to claim a reward is a scam.

Troubleshooting Fish It! Codes

Every code says invalid

Check your level first. Below Level 10 the game rejects every code regardless of whether it is valid. Fish until you hit Level 10, then try again. If you are past Level 10 and a single code fails, it is probably a typo or it has expired.

"Invalid code" on one code

The game shows the same message for a typo and for an expired code, so check both. Copy from the table rather than typing, keep the underscores and capitals, and scan the expired list above. If it is there, retrying will not help.

"Already redeemed"

Every code works once per Roblox account. If you redeemed it on your phone last month, it will not work again on PC, because the reward is tied to the account, not the device. Move on to the next one.

THEDEN, LEVDEN, or SCALEREFUND did nothing

These are tied to Leviathan's Den and the Leviathan quest. Visit the Den first for THEDEN and LEVDEN, and finish the quest before using SCALEREFUND. Redeeming them earlier either fails or gives nothing.

Listed as active but still not working

This game rotates codes weekly, so it may have expired since our last check, or your server may be running an older version after an update. Leave and rejoin so you land in a fresh server, then try again. If it still fails and the Last checked date is not today, it has probably just died and we will catch it on the next pass.
