Our notes on Lucky Block Challenge

What sets it apart

Lucky Block Challenge bundles ready-made maps built around the Lucky Block idea: a block that gives a random, often chaotic reward when broken. The project page says the maps range from a lucky block skyblock to a race against friends. The project’s short description also mentions Lucky OneBlock, Lucky Race, Lucky Games and Lucky Pillars, but the page gives no detail on those.

The mod list in our data shows a small, light base. Modern Lucky Block provides the blocks, Starter Kit and Paxi are also listed, and the rest is mostly performance and polish: Sodium, Lithium, FerriteCore, ModernFix, Entity Culling and Iris. Sodium Extra and EMI are there too.

The Modern Lucky Block page says the mod does not ship with a default Lucky Block addon, and that it is in early development with major changes expected, particularly in the structure of its JSON files. How this pack bundles the addon is not documented on either page.

Who it suits

Groups who want a short, silly challenge with friends, or players who like randomness-driven survival. Our categories mark it Adventure, Combat and Lightweight.

Before you install

The latest release is 2.1.2 on NeoForge for 1.21.1, dated November 6, 2026 in our data. Modrinth also lists a Forge build for 1.16.5 (1.1.1, August 2025), so confirm the loader and version before you download. The 2.1.2 changelog says lucky block temple spawns were increased by 30 percent.

The license is all rights reserved. The page lists no RAM recommendation and no known issues.

Which map suits which mode, and how to start each one, is not described on the project page.

Playing with friends

The pack is listed for client and server, with a Multiplayer tag, and our data marks both sides as required. Everyone needs the same version.

The page promotes hosting partners but gives no server requirements. Whether the race mode needs extra setup on a server is not documented.
