That's so cool to hear about the Nim game! I actually have never heard of it before. I guess the game I remembered was a variant of some kind. I remembered playing a math game with a teacher during recess back in elementary school. We would start at 0 and take turns adding 1 or 2 . We were trying to get to 21 first. It felt super unfair because it was a solved game and they always beat me. I added dice to that concept, flipped it to counting down and decided trying to avoid reaching the target number was more fun.
Thank you for playing! I'm glad you enjoyed our variant of these memorable math games!
