About Coal LLC Wiki

Who runs this site, and why it exists.

Coal LLC Wiki is a fan-created, unofficial reference for Coal LLC, a 2D side-scrolling mining game. The game doesn't have an official wiki, so this site exists to document its mechanics — block HP and drop values, passive upgrade math, chest loot odds, weapon stats — in a way that helps players make informed decisions without having to dig through forum threads or reverse-engineer the numbers themselves.

Who's behind it
