One Sheet Rules
A downloadable game
One Sheet Rules is an ultralite, classless, levelless game compatible with any OSR system such as Old School Essentials, Swords and Wizardry and Labyrinth Lord. You can learn One Sheet Rules in ten minutes and create a character in a minute or less. You can use the adventures and sourcebooks you already own. You can teach a nine year old to play in a couple of minutes. I did with my youngest son.

Release of the translation of William King's One Sheet Rules.
In addition, there is a character sheet. In English too.

These rules look great! Thinking of using them to play 1920s Lovecraftian horror. The character's occupation grants Advantage to one or two job-related skills. Seeing sanity-blasting sights requires an Int roll over 12, or the HD challenge rating of the Lovecraftian monster. If failed, the character takes 'mental damage' off their hit points. Not adding any rules, just interpreting Sanity loss as hit point damage as one's mind is shredded by alien visages, vistas, and concepts.
Sounds great, mate. I have been working on something similar although with more pulpy Robert E Howard/Brendan Fraser Mummy style fear rules. The other main rules additions are autofire weapons for things like Tommy Guns and a Hard to Kill rule for Eldritch Horrors. Basically roll damage as normal– if the result is 6+ you do 2 points of damage, otherwise you do 1. It works surprisingly well, particularly if you don’t tell the players about it.
Bill, that sounds fantastic! I'd love to see your Robert E Howard/Brendan Fraser Mummy style pulp rule set! Will it be posted soon online?
I have the rules written complete with monsters. I would like to do some more playtesting before I unleash them on the world.
Hi Bill, if you are looking for additional play-testers, I would enjoy participating. But if you are full up, totally understand that too. Either way, looking forward to this game - sounds wonderful! Cheers!
Would be happy to have you play-test it. Drop me a line at zine (at) onesheetrules (dot) com and I’ll send you a copy.
Hi, my name is Katya, I am a beginner programmer and game designer and I came across One Sheet Rules. I love RPGs and was impressed that you fit the rules on one sheet. I have translated it into Russian and if you want I can send it to you. I just thought, suddenly it will help someone who does not know English.
Thank you, Katya. I don’t have the skills (or the fonts) to do a Russian layout on one page but I could certainly add the text file.

Looks great. I would like to include you in the credits for this. Is that OK?
Sure!
Great! Thanks!
