Chaos Cubed is the second numbered Minecraft game drop of 2026, and it arrives on both Java Edition and Bedrock Edition on the same day. It brings the new Sulfur Caves biome, the block-absorbing sulfur cube mob, and two full building sets, so plenty of players want to know the precise moment they can log in and start exploring.
Quick answer: Chaos Cubed releases on June 16, 2026, expected at 10am CT (8am PT / 11am ET / 4pm BST). It launches as Java Edition 26.2 and Bedrock Edition 26.30, and both clients update automatically the next time you open them.
Release time: June 16, 2026 at 10:00 AM CT
Minecraft Chaos Cubed release date and time
The launch date is confirmed for June 16, 2026. Mojang does not announce an exact minute ahead of time, but its drops follow a steady pattern, so the most reliable estimate is a 10am CT go-live. In practice, updates tend to roll out between noon and 3:00 PM ET, sometimes earlier, so treat the times below as the expected window rather than a fixed clock.
| Time zone | Release time |
|---|---|
| PT | 8am, June 16 |
| CT | 10am, June 16 |
| ET | 11am, June 16 |
| BST | 4pm, June 16 |
| CEST | 5pm, June 16 |
| JST | 12am, June 17 |
| AEST | 1am, June 17 |
You will know the update is live when your client downloads the new version and the main menu panorama switches to the Chaos Cubed scene. On Java, look for a new row of buttons above Options, including the Java friends list icon. If your client still shows the older version, fully close and reopen it to trigger the update.
Version numbers: Java 26.2 and Bedrock 26.30
Since December 2025, Mojang uses a year-based numbering format instead of the old 1.x scheme. The first number is the two-digit year, the second is the drop within that year, and the third is a hotfix counter. That makes Chaos Cubed the second drop of 2026 on Java as 26.2, while Bedrock counts from a higher base and labels the same release 26.30. It follows 26.1 “Tiny Takeover,” which arrived on March 24, 2026.
What’s new in Chaos Cubed
The drop centers on the Sulfur Caves, a new underground Overworld biome built from yellow sulfur and red cinnabar blocks, with sulfur spikes forming stalactites and stalagmites along the walls and floors. Greenish sulfur pools sit at the heart of the biome, with potent sulfur at the bottom that fills nearby water with noxious gas and inflicts the Nausea effect on anyone who wades in.
The signature mob is the sulfur cube, a passive slime-like creature that hops around the caves. Give it a block and it absorbs it, entering an immobile, damage-immune state where you can knock it around like a ball. The block inside changes how it behaves, so wool makes it floaty, ice makes it slide, logs make it bouncy, and TNT lets it ignite and explode. Like other slime mobs, it splits into smaller cubes when killed, and you can scoop one up with a bucket or place one with its spawn egg.
Geysers are the other headline addition. They form where potent sulfur sits above magma or lava and erupt on a short cooldown, launching players, mobs, and items upward without dealing eruption damage. Geysers can also generate on the surface in any biome, working like a natural marker that hints at Sulfur Caves hidden below.
New blocks, items, and music
Builders get two complete decorative sets in a yellow-and-red palette. Each comes with polished variants, bricks, chiseled versions, and matching stairs, slabs, and walls.
| Set | Includes |
|---|---|
| Sulfur | Sulfur, polished sulfur, sulfur bricks, chiseled sulfur, plus stairs, slabs, and walls. Potent sulfur and sulfur spikes round it out. |
| Cinnabar | Cinnabar, polished cinnabar, cinnabar bricks, chiseled cinnabar, plus stairs, slabs, and walls. |
Four sulfur spikes craft into a sulfur block, and four spikes can also be combined to extend stalactites and stalagmites. The update adds the “Bounce” music disc by fingerspit, found in mineshaft chest minecarts inside the Sulfur Caves, along with five new background tracks for the Overworld and main menu. A bucket of sulfur cube and a sulfur cube spawn egg are the new mob items.
Cave spiders and the Java friends list
For the first time, cave spiders spawn naturally in the world, appearing in the Sulfur Caves in place of regular spiders. Until now they only came from mineshaft spawners and trial spawners. Java Edition also gains a built-in friends list with online status and peer-to-peer connections, accessible from a new button row above Options, removing the need for a dedicated server or Realms just to play with friends.
Java players can additionally try an experimental Vulkan renderer that sits alongside the existing OpenGL option in graphics settings. It is opt-in, so the default experience stays the same unless you switch to it, and results vary by hardware and graphics driver.
How to install Chaos Cubed
Once the update is live on June 16, both Java and Bedrock clients update on their own the next time they launch, so most players do not need to do anything. If you would rather test the build early, the latest snapshot can be enabled inside the Minecraft Launcher before you press Play.
Note: New releases can corrupt older worlds, so back up any save you care about before loading it in a snapshot or the new version.
If you play on a server, hold off on day-one upgrades for plugin-heavy or modded setups. Vanilla and small private servers can usually update on release, but Paper, Spigot, and most mods need a few days to publish builds that target 26.2.
If you are counting down to June 16, set a reminder for your local time from the table above, and remember that the exact minute can shift slightly on the day. As soon as your client pulls the new version and the Chaos Cubed panorama loads, the Sulfur Caves are ready to dig into.
