From the publisher website: Cthulhu Dark Cthulhu Dark is my rules-light Lovecraftian game. (Or try the easily-printable version). The rules are fun and incredibly minimal: they fit on one sheet of paper. You don’t need a character sheet to play, so you can start playing after two minutes of prep. Despite the simplicity, there are some interesting rules twists: look at the Suppressing Knowledge rule for an example. For your first game, use the main rules alone. Run a prewritten scenario with a Keeper. Then, if you like, check Dark Experiments to see additional rules I’m working on.
