ClassiCube is a replica of Minecraft in classic versions phase during 2009. After Mojang shutted down the Minecraft Classic website and servers, some people decided to revive the great service. At this moment ClassiCube is focused on letting players connect to multi-player servers and Enchanced Mode, which will we talk about in the next section.

Besides original Minecraft Classic experience, ClassiCube bundled its own modifications and improvements, such as hacks (flying, noclipping, speeding), which in fact has been already implemented in older, hacked Java clients. ClassiCube also supports custom textures, blocks, client-side and server-side plugins, level environment settings, and way more improvements included in Classic Protocol Extension. All of that, combined or not, gives full modularity and enchancement to the game.

The most popular ClassiCube server of all time is Not Awesome 2 with over 60 thousand unique player logins. There are also popular minigames servers like Good old lava survival or New Blood [Zombie Survival]. Other interesing servers are MINESWEEPER and Infinite Backrooms.
