The latest Fish It update brought a brand new machine to Underwater City, the Atlantis Machine. If you've been piling up fish and are not sure what to do with the extras, this machine finally gives them purpose. Here is how to use the Atlantis Machine in Fish It.
What Is the Atlantis Machine in Fish It?
The Atlantis Machine is a new feature inside the Underwater City POI. It works like a sacrifice system, where you donate fish to the machine, collect points, and those points unlock a random booster. The booster then gives you a temporary buff that you can use right away during your next fishing run.
It's a solid way to make use of fish you weren't planning to keep. And honestly, the boosts you get back can make a real difference — especially if you're grinding for something rare.
How to Use the Atlantis Machine in Fish It
The process is pretty straightforward. Here's how to do it step by step:
- Head over to Underwater City and find the Atlantis Machine.
- Select your fish to donate — you can do it one by one or all at once.
- Earn points based on the total number of fish you submit.
- Collect your random booster as your reward.
All Atlantis Machine Boosters
There are five different boosters with 20% drop chance each that the machine can give you. The one you get is random, and each one lasts for a different amount of time depending on what the machine rolls.

| Booster | What It Does | Duration Options |
|---|---|---|
| Luck Surge | Raises your odds of catching rare fish | 30 min / 1 hour / 1.5 hours |
| Mutation Surge | Boosts the chance of getting mutated fish | 30 min / 1 hour / 1.5 hours |
| Speed Surge | Makes your fishing faster overall | 30 min / 1 hour / 1.5 hours |
| Big Catch Surge | Increases the size of the fish you reel in | 30 min / 1 hour / 1.5 hours |
| Shiny Surge | Raises the odds of catching shiny fish | 30 min / 1 hour / 1.5 hours |
Tips for Getting the Most Out of the Machine
The Big Catch booster works a lot like the Big Hunter enchant in the game, just as a timed buff instead of a permanent upgrade. If you get this one, jump straight into fishing. Don't let the timer run out while you're doing other things.
If you're hunting the Eater (a time-limited fish in the current update), stacking a Luck booster on top of your session is a smart move. One thing worth keeping in mind: save up a decent stack of fish before visiting the machine. The more you donate in one go, the more points you get, and that means a better shot at landing a longer booster duration.
The Atlantis Machine is one of the best new additions in Fish It latest update. It turns leftover fish into something useful and gives you a reason to plan your fishing sessions more carefully. For more codes, tips, and game information, you can always visit our dedicated Fish It wiki.
