Blacky the Blackball
Gratis Games is not a publishing company, games company or an organisation of any kind. It is simply the (rather pretentious) name of a website.
Back in 2009, someone logged on to a D&D message board (The Piazza) and - needing to pick a username - thought up the name "Blacky the Blackball" (named after the blackball monster from the D&D Rules Cyclopedia) and started discussing D&D. Before long, during a discussion about retro-clones of old games, the poster rather rashly declared that he was going to write one.
That poster was me, and the game was Dark Dungeons.
While I was writing Dark Dungeons, it had its own development blog; and after it was finished that blog was turned into a static website for the game where it could be downloaded. However, since releasing Dark Dungeons I have also created other things - other RPGs, a roguelike computer game, and more.
