I am sure there are more nano-RPGs out there with a few words or less. Please share them here if you know of any. I am going to put all suggested itch.io games onto the list of examples. (I try not to use Twitter too much as a source, but I am happy to link to RPGs from other non-social media sites.)
In 2017 there was a challenge of writing a game with 270 characters, and I created a game called Warrior (with 53 words):
"Characters have 1-10 HP. Initiative is 0 or 1. Players in a duel cross hands, then call odds or evens with none, one or adding up two hands. Each opened hand causes 1 DMG, and each closed hand absorbs 1 DMG. Winner gets +1 permanent HP and decides the fate of the loser."
hey! Well, if we're sharing things we've already made, I make hyper-simple little, I guess they're ttrpgs although they tend to be a little light on the roleplaying aspect, paired with illustrations--in terms of size, this here is probably the smallest one that's actually any good (twenty-something words--i counted the # of words, but then I forgot while typing this comment >_<): https://lizziesmithson.neocities.org/Zines#135
game jam sounds fun! I already have some vague ideas of stuff i'd like to submit, I hope that doesn't count as cheating lol
There is something similar I would recommend looking at, called micro-fiction where the entire game is text based with 280 characters or less: https://microfictiongames.neocities.org/
