Jelly Operator was introduced for patch V1.22 on 18/09/2026.

Jelly Operator Overview

The Jelly Operator can be found in World 7 Shimmerfin Deep: Jellofish Fields. Once unlocked, it will then be accessible from the World 7 home map Shimmerfin Grove.

Inside the Jelly Operator UI, you'll see a bunch of locked grid slots and a giant Obstruction in the middle. Each obstruction has to be defeated by Jelly Cells when you click on the Start Operation button.

You can place different types of Jelly Cells that you have unlocked in your Petri Dish onto any unlocked grid slots.

Each Jelly Cell has a different effect and purpose that affect how your Operations unfold.

When you've placed Jelly Cells on your grid, click Start Operation. Your Jelly Cells will then attack the Obstruction, dealing damage over time. When the operation time runs out, it's game over.

If you manage to defeat the Obstruction during the operation, you gain a new account-wide bonus. 

You get 2 lives per day, but more can be unlocked from the Research Grid G3.

Your Jelly Cells can also gain EXP by dealing damage. When they level up, their damage and bonus effects increase.

Jelly Operator Boss / Obstructions

Here you can find all the Jelly Operator Bosses and Obstructions. They must be defeated in order of the list below.

The amount of time you get during operations increases every 12 bosses.

Jelly Cell Types

Below you can find all the different Jelly Cells you can place on your grid. Each cell is unlocked through Jelly Operator Upgrades.

Jelly Operator Upgrades

Below you can find all the Jelly Operator Upgrades that help boost your operations against bosses!

Each upgrade requires you to have at least one level in the previous upgrade and a Research Level requirement.

Jelly Operator Guide

Jelly Operator is a new addition to World 7 and as such, there are not that many bonuses you can get from other areas of IdleOn to make this game a cake-walk.

That being said, there are plenty of tactics to draw upon to start meaningful progression.

Max Your Daily Plays

First and foremost, make sure you max the Research Grid: Daily Operating Procedure. This will give you +6 operations per day, allowing you to make much more progress than you would with just the default 2 plays per day.

When you unlock the Daily Transfusion Jelly Upgrade, you should always try to push this upgrade to the max. It gives a massive Bloodcell Bonus every day, which is usually the equivalent of one or two extra plays of Jelly Operator.

Cell Levels

Whenever you have a cell added to your grid during an operation, they'll gain EXP and can level up, further boosting their stats.

There are also several Jelly Upgrades that will boost your damage and Bloodcell rates based on cell levels:

• Cell Biology - EXP that each cell earns is boosted and each level a cell has boosts it's damage by 1.05x
• Cell Dialysis - Boosts Bloodcell rates by % for each Cell Level you have (total)
• Cell Mutation - Each cell gains a % DMG Multi for level it has
• Cell Metabolism - Gain % DMG for all total levels

As you can see, there are a few upgrades that are boosted by all your cell levels combined, so it's a good idea to give other Jelly cells a chance on the grid to gain EXP. You'll probably want to do this when you're no-where close to beating a Jelly Obstruction Boss.

Early Game Strategy

The best damage dealing cell in the game has to be the first one you unlock: Amoeba.

It only takes up one grid slot, gives a passive +10% damage and will be the cell that racks up your damage multi during operations. The upgrade Immuno Weakening gives you the damage multi which increases each hit from your Amoeba.

The Plasmid Cell has a higher DPS, but this is cancelled out by the fact that Immuno Weakiening adds a multi. It does give a +15% All SPD boost to other cells on your grid, so you want a few of these dotted around.

The Ribosome isn't very good; it will stop operating when hit and takes up 3 grid slots. It's passive +50% All DMG isn't great either; you'd rather have 3 Amoeba that give +10% and contribute towards your damage multi. Having one Ribosome is enough.

When you unlock the Organelle that's where things get more interesting. Organelle will boost surrounding cells that touch it with a 1.5x SPD Boost- so you want to place them on the grid where as many cells can tough it as possible. You should try and stack as many Organelle on top of each other, as they will then boost each other too!

In terms of what grid slots to unlock, focus on getting height on one side of the grid. You can really put yourself at a disadvantage if you just choose random slots! Height allows you to stack more Organelle without them wasting slots on a double-touch cell.

Ferverizer

The Ferverizer has several different modes you can unlock through the Jelly Upgrades.

In early-game, you'll want to use the RASH status (level 2 Ferverizer upgrade). This gives a 2x damage bonus to all cells, right from the get go. 

Cold gives 1.01x damage per second, and even when you add in several Immunoid cells to slow down the operation, you still end up with more damage dealt. This might get better the bigger your grid is; to get up to 2x damage, your operation needs to last at least 100 seconds.

Stronkroid

The Stronkoid upgrade gives you a tiny 5 second speed boost to all cells.

The idea behind this mechanic is to use it exactly when you can reach your max DPS- the area is when you reach Critical Condition and have only lost a few cells.

Combining this with Immunoid Cells doesn't really boost your max DPS very much because you lose out on the extra DPS you'd get from having attacking Amoeba cells.

It might work if your grid is big enough to last more than 100 seconds, switch to Cold Feverizer and have enough Immunoid Cells where you can get your multi high enough.
