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."
