6T4 Challenges
by Angel6T4mc
6T4 Challenges is a Fabric minigame mod for Minecraft 1.21.11 that adds a growing set of unique challenges, toggled from a 6T4 button on the title and pause screens.
What it does
Players open the 6T4 menu from the title screen or the pause menu to switch challenges on or off, configure each one separately and combine several at once. Most challenges expose their own options for intensities, distances and difficulty, and a few modifiers apply global tweaks across the active challenges. Changing a challenge can require a restart before it takes effect.
The mod was built with content creators in mind, and the author plans to keep adding challenges until the set reaches 64 or more, with seasonal challenges along the way. A challenge screen shows whether it works in multiplayer. Fabric API is required, and the mod runs on client and server, so the server and every player need it. Files are published for Fabric only, for 1.21.11, and the code is released under All rights reserved, so the mod is not open source.

How it compares
ChallengeMod is open source under the MIT License and covers Fabric builds for 1.21.5 – 1.21.10, so it does not reach 1.21.11. No Health Bar is client-side only and released under All rights reserved, for 1.21.1 – 1.21.3. Chunk Challenge is a server-side challenge mod for 1.21.11 under the MIT License, so only the server needs it and players join without installing it.
