Block Randomizer
by LeLe-YT
Block Randomizer assigns each block type a single random item drop, so breaking a block for the first time gives a fixed reward that stays the same for the rest of the world.
What it does
Each block type receives one item from the full item list the first time a player breaks it. That item is then assigned to the block type and every later break of that block drops the same item for the rest of the session. Only one item drops per block, which keeps the randomness predictable once a player has learned the assignments. The mod is a server-side only Fabric mod, so players join a server running it without installing anything. A command starts the challenge and enables the randomizer, and a sound plays as feedback when the command runs.
The mod is built for a simple challenge that works in survival runs, SMP events and other randomizer-style play. It works in single-player and in multiplayer, and the assigned drops stay consistent across the entire world. Block Randomizer is released under the MIT License and is not open source. Files are published for Fabric and cover only Minecraft 1.20.1, with version 1.0.2 as the latest file dated 2026-05-15.
Key features
First-break assignment
Breaking a block type for the first time draws one item from the entire item list and locks it in.
Consistent drops
The assigned drop stays the same for that block type across the whole session and the rest of the world.
Start command
A challenge command starts the game and enables the randomizer, with sound feedback when it runs.
Single-item drops
Each broken block drops only one item, so the outcome of each break is clear to read.

Use cases
Survival challenge runs
Players can use the randomizer as a challenge that changes which blocks yield which resources.
SMP events
Server owners can run a shared randomizer session for a group of players during an event.
Who it’s for: Players and server owners looking for a simple randomizer challenge on Minecraft 1.20.1. Because it runs on the server alone, a server can host it without requiring installs from players.
How it compares
Effect Randomizer is open source under the MIT License and runs on Fabric, Forge and Quilt for 1.20.2 – 1.20.4, where the server needs it and the client may skip it. Q-Inventory Randomizer is also server-side only and MIT licensed, but is not open source and covers 1.20.1 – 1.20.6. Block Randomizer is limited to Fabric and 1.20.1, so it fits only that version.

What the author says
Randomizer Mod changes Minecraft by giving every block a unique random item drop. When a block is broken for the first time, it receives a random item from the entire item list. From that point on, that block type will always drop the same assigned item for the rest of the world. This creates a simple but fun…
