I ran a game for my niece the other day not using any specific rules just the sort of default osr-ish rules in my head. So I decided to write those rules down. They are not original. 3d6 stats, d20 roll under. Basically the Black Hack but sloppier and less complete. I wrote it in pocket mod format on procreate using this template: https://mr-matthew.itch.io/one-page-zine-template-procreate.
One sheet of paper folds into a book with character sheet and rules included so you can give one to each player. for info on how to fold them go here: https://pocketmod.com/howto
Some things not covered in the rules but probably should have been are:
Monsters. Stats need for monsters are Energy (basically HP) and Damage (usually d6).Advancement. Let PCs level up every once in a while. They can raise an ability score by one (max 18), or learn a new special.
Included is CAVERN OF THE WORM, a little pocket dungeon for NOSR!
