Stone Box is a semi anarchy factions server where the whole world is basically stone. There is no overworld so you are stuck living in the box and everything you do comes from base game knowledge plus special gens that are hidden around the map.

You can make or join a team then build a weird base or raid someone else. Politics is a real thing here too and some players treat it like their own story even though it is not a roleplay server. The server is over five years old and there is lore hidden in the world and in archives.

Structures can generate inside the stone and people fight over them because they are big hotspots. Season 4 just started so it is early and most players are setting up teams and bases.

There are lots of weekly events like spleef hunger games and ctf. There are also build contests video stuff and even in game political events like meet ups or player weddings.

It is free to play on every platform. The combat is java style and it is integrated for bedrock users. The only real non vanilla thing mentioned is a team home command with a thirty minute cooldown and a two day wait after switching teams before you can use it.
