Chaos Randomizer
by wenjah
Chaos Randomizer is a Fabric minigame that turns a Minecraft session into a timed run of random objectives, with a roulette reveal before the challenges begin.
What it does
Each session starts with a roulette animation that assigns the player a set of objectives. The player then has to complete the challenges before a countdown timer runs out, and a game over screen appears if time expires first. The goal is to defeat the Ender Dragon, which counts as the win condition after the challenges are met.
The mod draws from more than 40 challenge types, including killing mobs, mining blocks, reaching XP levels and wearing a full armor set. Chaos events trigger on a timer whose interval the server can set, defaulting to 10 seconds, and may cause teleports, random items, potion effects, mob spawns, lightning or shifts in weather. Before starting, the player can re-roll the assignment up to three times. The interface is bilingual in English and French and follows the Minecraft language setting. The environment is client and server, so the server and every player need the mod, and the code is not open source, under All rights reserved.
Key features
Roulette objective reveal
An animated roulette shows the assigned objectives before the timer starts, so each run opens with a clear list of tasks.
Forty-plus challenge types
Challenges cover combat, mining, XP progression and armor, and the player chooses how many to take on within the time limit.
Chaos events
Random events such as teleportation, mob spawns, lightning and potion effects fire at an interval the server can set, 10 seconds by default.
Re-roll and timer
Up to three re-rolls are available before the run begins, and a visible countdown ends the session with a game over screen when it runs out.

How it compares
BlockDropRandomizer is a Fabric mod for 1.21 – 1.21.11 under the MIT License and is not open source, so it randomizes block drops rather than whole sessions. Mobber is Server-side only, open source under the MIT License and published for 1.21.10, which changes mob behavior without a timed objective list. Portal Randomizer is Server-side only, open source under the CC0 1.0 Universal license and published for 1.21.8, so it affects portals only.
