How to Install Lucky Block Add-ons

Lucky Block add-ons are extra JAR files that expand what your Lucky Blocks can drop, adding new bosses, structures, armor sets, or themed content packs. They go in the same mods folder as the base mod and load together with it. The process is simple, but a version mismatch or a missing base mod will crash your game every time.

What You Need Before You Start

• Minecraft Java Edition: add-ons use the Forge mod system and have no Bedrock equivalent
• Minecraft Forge installed and working: nearly all Lucky Block add-ons require Forge; if you have not set it up yet, follow our Forge installation guide
• The base Lucky Block mod already sitting in your mods folder; add-ons depend on it directly and will not run without it
• The add-on .jar file you want to install, downloaded from a reliable source

How to Install Lucky Block Add-ons

1. Check which Minecraft version you are running

   Open your Minecraft launcher and look at your Forge profile. Note the exact version number, for example 1.12.2 or 1.16.5. You need this to match the add-on in the next step.

2. Match the add-on to your exact Minecraft version

   Lucky Block add-ons are version-specific. An add-on built for 1.12.2 will not load on 1.8.9, and the game will crash if you try. Check the add-on’s download page and confirm the version tag matches yours exactly before downloading.

3. Verify the base Lucky Block mod is in your mods folder

   Navigate to your mods folder and confirm the Lucky Block JAR is already there. On Windows, open File Explorer and go to %AppData%\.minecraft\mods. On Mac, check ~/Library/Application Support/minecraft/mods. On Linux, it is at ~/.minecraft/mods. If it is missing, install the base mod first before doing anything else.

4. Download the add-on JAR

   Get the .jar file for the add-on. If your browser saved it as a .zip or added a .jar.zip extension, rename it so it ends in .jar only. Do not extract it; it goes into the mods folder as-is.

5. Drop the JAR into the mods folder

   Copy or move the add-on JAR directly into the same mods folder where the base Lucky Block mod lives. There is no special add-ons subfolder. Add-ons go in the same location as every other Forge mod, right alongside the base Lucky Block JAR.

6. Launch Minecraft with your Forge profile and test

   Start the game using your Forge profile. Load a world, get a Lucky Block, and break it. If the add-on loaded correctly you will see its drops appearing. You can also click the Mods button on the main menu and look for the add-on name in the list to confirm it registered properly.

Common Mistakes and Troubleshooting

Game crashes immediately on startup

This is almost always a version mismatch. The add-on JAR, the base Lucky Block mod, and your installed Forge version all need to target the same Minecraft version. Even a small difference like 1.12 vs. 1.12.2 will break things. Open the crash log (found at .minecraft/crash-reports/) and look for the mod name in the error to confirm which file is the problem.

Add-on does not appear in the Mods list

The file is probably not a valid JAR. Some download sites serve the file as a ZIP and browsers do not always rename it correctly. Check the file extension. If it says .jar.zip or just .zip, rename it to remove the extra extension. Only the .jar file goes in the mods folder.

Seeing base Lucky Block drops but nothing from the add-on

The add-on loaded but its content is not appearing. This can happen if the add-on requires a newer version of the Lucky Block mod than you have installed. Check the add-on’s page for a minimum Lucky Block version requirement and update the base mod if needed.

Missing dependency error in the crash log

The add-on is telling you it cannot find what it needs. The base Lucky Block mod may be missing or the wrong version. Replace it with the correct version for your Minecraft version and try again.

Running multiple add-ons at once

You can install as many add-ons as you want. Drop all the JARs into the mods folder. Each one adds its own drops to the pool. If something breaks after adding a second or third add-on, remove them one at a time to find which one is causing the conflict.

Which Versions and Editions This Applies To

Lucky Block add-ons are Java Edition only. Bedrock Edition has its own behavior pack system, which is a completely different format and is not covered here.

The largest selection of add-ons exists for Minecraft 1.12.2, which is the version most of the Lucky Block community built around. There are add-ons for 1.7.10, 1.8.9, 1.16.5, and 1.18.2 as well, but the options get thinner as the version number goes up.

Most add-ons require Forge. If you want to use Fabric or NeoForge, check the specific add-on’s page to see if it lists support for those loaders. The majority do not, but a small number of newer ones do. For general mod installation steps that apply here too, see our guide on installing mods with Forge.
