Minecraft Lucky Block Servers
Lucky Block is a minigame built around "lucky blocks": when broken, such a block gives a random result from many options — from valuable loot and weapons to hostile mobs and traps. You never know in advance whether you will get lucky, and it is precisely this unpredictability that makes the game exciting. Most often Lucky Block runs in a race format: players break blocks in a rush, gather gear and clash in a final fight. It is a dynamic and fun minigame where luck and reaction matter more than long preparation.
This page lists 32 Lucky Block servers; each project's player count is verified by direct ping. Implementations vary: on some it is a server plugin (you can play with an ordinary client), on others a mod pack. If you like fast competitive minigames, take a look at PvP servers; if projects with a set of minigames interest you, visit servers with minigames.
