How To Enable Experimental Features In Minecraft Bedrock | T

To enable experimental features in Minecraft Bedrock Edition, toggle the switches in the Experiments section of a world’s Game settings and confirm the popup.

Experimental features in Minecraft Bedrock Edition give you early access to upcoming content like the Update 1.21 Crafter or the latest biome changes before they fully release. The toggle itself is straightforward, but enabling it comes with a few permanent rules that catch many players off guard. Here is how to enable experimental features in Minecraft Bedrock Edition for new and existing worlds, what the toggle actually does, and the one thing you cannot undo.

What Are Experimental Features in Bedrock Edition?

Experimental features are unfinished gameplay elements—blocks, mobs, mechanics, and world-generation changes—that Mojang bundles into test toggles. These are not finished content. They may contain bugs, break existing builds, or get removed entirely in later updates. Activating an experimental toggle signals that you accept those risks in exchange for trying the features early.

How to Enable Experimental Features in Minecraft Bedrock Edition

The steps differ slightly depending on whether you are starting a new world or modifying an existing save. Both methods go through the Experiments section in the world’s Game settings.

For a New World

1. Click Create New World to open the world settings.
2. Click the Game tab on the left sidebar.
3. Scroll down to the Experiments section.
4. Flip one or more toggle switches ON.
5. When the popup appears asking “Activate Experimental Gameplay?”, click Activate Experiments.
6. Finish creating the world normally.

For an Existing World

1. On the Worlds screen, find the save you want to modify and click the Pencil icon (Edit World).
2. Click the Game tab on the left sidebar.
3. Scroll down to the Experiments section.
4. Flip one or more toggle switches ON.
5. Click Activate Experiments in the popup.
6. The game automatically creates a copy of your world named “Copy of [Original World Name]”. This is the experimental version; your original world remains untouched.

An Experimental tag appears next to the game mode in the Worlds list. The enabled experiments are also listed inside the world’s Game settings under the Experiments section.

Minecraft’s official experimental features toggle documentation provides the same walkthrough.

Which Experimental Features Are Available?

The toggles available change across versions as features graduate to the full game or get retired. As of the latest Bedrock Edition updates, these are the commonly available experiment sets:

The exact list on your screen depends on your game version. Beta and Preview builds usually have additional toggles that have been removed from the retail release. For example, the Caves & Cliffs (Part I) toggle is no longer available in Beta because those features are now fully integrated.

Common Mistakes That Cause Problems with Experimental Features

Assuming you can disable experiments later. This is the most frequent error. Activating experiments is a permanent decision for that world file. You cannot un-toggle an experiment or convert the world back to a non-experimental state. The world remains tagged Experimental permanently.

Enabling experiments directly on a Realm. Bedrock Realms do not have an Experiments toggle in their settings. You must edit a copy of the world offline with experiments enabled, then replace the Realm world with the modified file. The same limitation applies to most dedicated Bedrock servers.

Panicking over the world copy. When you enable experiments on an existing world, the game creates a backup copy automatically. Your original save is preserved exactly as it was. The new “Copy of…” file is the one that gets permanently altered.

Understanding the Real Risks of Enabling Experimental Content

Crash risk is real. Because the features are not fully tested, they can cause world corruption, crashes, or broken chunks. Mojang explicitly warns that experimental worlds may become unplayable with no way to recover them besides a backup.

Future update incompatibility. Features are sometimes cut or radically reworked. A world that relies on a removed experimental feature may stop loading or lose entire chunks when the full update releases. Always keep a stable backup before activating experiments.

Resource pack limitations. As of version 1.21.90.1, the new Bedrock UI prevents editing experiments directly through resource packs. If you need custom adjustments, you must use the third-party Minecraft Bedrock Experiments Editor web tool instead.

Best Method for Every Scenario

Consolidated Steps for Enabling Experiments Safely

If you walk away with one workflow, this is it:

1. Back up your important worlds — even though the game makes a copy, manually backing up guarantees nothing is lost.
2. Open world settings -> Game tab -> Experiments section.
3. Toggle on the experiments you want and click Activate Experiments.
4. Look for the Experimental tag on the world select screen to confirm it worked.
5. Do not attempt to deactivate experiments — the only way to revert is to load your original backup.

Treat experimental worlds as temporary test-drives. Enjoy the early access, explore the new content, and keep your main survival world untouched.
