Randomizer Block
by Kootryne
Randomizer Block gives a random output from a single block, so a player who places one at a trigger receives a different result each time it is used.
What it does
A randomizer block picks one output at random when it is activated, with each of its six sides carrying a dot that marks the output side. Builders use it to create games of chance inside a world, such as dice rolls, casino machines and puzzle maps where the outcome is not known in advance. The random output is what lets a single block serve as the core of a minigame.
Adventure maps and minigames are the main use cases the author describes, where the block supplies the random event the design depends on. Fabric API is required, and the mod is licensed under the MIT License, but it is not open source. It is published only for Fabric and only for game version 26.1.2, with build 1.0.0 released on 2026-04-28. Because it runs on both client and server, the server and every player need it installed.
Key features
Random output
Each activation of the block gives a random result, so the same block can produce different outcomes over time.
Casino machines
The block can serve as the random core of a casino machine built in a world, with its results unknown to the player.
Puzzle maps
Puzzle maps can use the block to place an unpredictable element that a player must work around or solve for.
Making dice
A player can build a dice roll from the block, giving a random result on each use without any extra commands.

Use cases
Adventure maps
Map makers can place the block where a random event is needed, so each playthrough of the map differs.

Minigames that depend on a random event can use the block as the source of that event.
Who it’s for: Map makers and server owners who build minigames, casino machines or puzzles in Minecraft Java Edition 26.1.2 with Fabric. Players join servers that run the mod without any extra setup beyond the shared install.
