The Block Shuffle

An admin starts a game and the mod gives every connected player a random target block. Once the round begins, a countdown runs while a boss bar displays the time left in the current round, and a sound plus a chat message fire when half the time has passed. Each participant receives an individual target, so the race is not a single shared item. The last player standing wins.

Difficulty rises with each round. Level progression draws from lists of rarer, harder-to-find blocks, and the level increases up to a configured maximum, with blocks already used removed from the pool. Biome filters and a block blacklist control which blocks can appear, including Nether- and End-exclusive blocks, while problematic items such as the Dragon Egg, Beacon, Conduit and Sponges are blocked by default. When a connected player goes offline, the mod takes them out of the current round automatically, so the rest of the group keeps playing uninterrupted.

The mod runs on Fabric and is published for 1.21.8 – 1.21.11, with version 1.0.0 for 1.21.11 as the latest file. Both the server and every player need it, and it is licensed under All rights reserved, so it is not open source.
