Jujutsu Farm: How to Get and Open Sealed Cubes

Quick answer

Buy a Sealed Cube from the ROLL conveyor at your plot or from the MARKET rotating shop in the plaza, open it on your plot's conveyor, and when the opening countdown ends the cube produces a Jujutsu Kaisen character with a prefix, a name, a level and an income value shown in $/Orb.

• Get one: click ROLL at your plot conveyor, then pay the shown cash price via Purchase or place the cube directly.
• Open it: the placed cube runs an opening countdown on your plot conveyor, with a Skip Open Time option shown during the opening.
• Reward: the finished cube places a character on your plot that earns money per Orb.

Opening a sealed cube is the core loop of Jujutsu Farm. The game's own How to Play guide lists opening Sealed Cubes as the first step, because each cube unlocks a Jujutsu Kaisen character, and placing that character on your plot generates the money that funds better cubes and upgrades. Here is the full path from an unopened cube to a character earning cash on your farm.

How to get a Sealed Cube

1. Go to the conveyor at your plot. This dispenser machine carries the ROLL! button, and its level is shown right on it — for example, one Conveyor at Level 5/15 was offering Cursed Womb, Mahito's Experiments, Kyoto Goodwill and Death Paintings cubes.
2. Click ROLL. Every roll makes the conveyor generate a random Sealed Cube, and each cube comes with a variant. Observed variants include Normal, Cursed, Black Flash and Special Grade.
3. Buy it or place it. After a roll you can pay the cube's shown cash price via Purchase to store it in your backpack, or place it directly. Rolling again produces the next random cube, so you can compare what each roll gives before deciding.

The conveyor guide explains the machine itself in more detail.

Getting cubes from the MARKET

A second source is the MARKET (Rotating Shop!) stall in the plaza, which sells Sealed Cubes for cash. Stock and prices rotate, and each offer can be bought once per rotation. In one observed rotation, a Cursed Death Paintings Sealed Cube was on sale for $128M and flipped to BOUGHT once purchased — so if you want a cube from the current lineup, buy it before the rotation changes. The cube market page follows the stall's offers in detail.

How to open a Sealed Cube

Opening happens on your plot's conveyor:

Mechanic flow

1. 1

   Place the Sealed Cube on your plot conveyor

   Cubes are opened on the conveyor — a placed cube starts its opening countdown there.

2. 2

   The opening countdown runs

   A timer counts down while the cube opens, and a Skip Open Time option is shown during the opening.

3. 3

   The cube produces a character

   When the countdown ends, the cube produces a character with a prefix, a name, a level (Level 1 in the observed opening) and an income value shown as $/Orb, together with an upgrade button.

Shortening the wait

• Skip Open Time — shown on the cube while its opening countdown is running, for skipping that cube's timer.
• Open Time Boost — sold in the plot's UPGRADES panel; its in-game description says it reduces opening time for lockers.
• Robux shortcuts — the game sells Skip Open Timer products matched to timer lengths (under 5 minutes, 10 minutes, 30 minutes, 1 hour, 2 hours, 4 hours and 6 hours), plus Reduced Sealed Cube Time and Skip All Cube Timers.

Exact opening times per cube type aren't documented, so read the countdown on your placed cube to see how long yours will take. The cube opening time page gathers what is known about the timers.

What you get when the opening finishes

When the countdown ends, the character appears placed on your plot and generates money per Orb. The result shows:

• The character's prefix and name — the observed opening produced Star Nanami from the Mahito's Experiments tier
• A level — Level 1 in that same opening
• An income value shown as $/Orb — the cash the character generates
• An upgrade button

That opening is a useful benchmark: an eye-patterned Sealed Cube opened into Star Nanami (Mahito's Experiments) at Level 1 earning $18.50K/Orb. Tapping the upgrade button repeatedly raised her to Level 29, which lifted her income to $1.90M/Orb. The character you pull is a starting point, then — placed characters can be leveled up, and upgrading is how a Level 1 pull becomes a serious earner. See how to place characters for arranging your plot and how to upgrade characters for leveling them.

Quests that ask you to open cubes

Opening cubes isn't only about income — some quests track your openings directly:

• The Malevolent Shrine limited-time quest "Day 1: Open 10 Sealed Cubes" asks for ten openings.
• Kogane's RULE 4 tasks include "Open a new Cursed Variant character" — an explicit reason to open cubes with variants rather than only the first cube you get.

Cube types and variants at the conveyor

The conveyor's settings panel lists the game's cube types in tier order, from the earliest Cursed Child cubes up through Shibuya Incident I:

Cursed Child → Jujutsu First Years → Cursed Womb → Mahito's Experiments → Kyoto Goodwill → Death Paintings → Hidden Inventory → Curse Users → Disaster Curses → Shibuya Incident I

That is the sequence shown in the panel; more cube tiers exist beyond Shibuya Incident I in the game's shop catalogue. Variants ride on top of the tier — Normal, Cursed, Black Flash and Special Grade were all observed during play. The same panel also lists the paid Auto Conveyor options (Robux): Auto Buy, Auto Spawn and Variant Selection. For the full roster of cubes, see the sealed cubes list.

Once your first cube opens, the loop repeats: placed characters earn the cash that pays for your next rolls and upgrades, and quests check in on your openings along the way. If you're just starting out, the beginner guide puts cube opening in the context of the whole game.
