Yes, it was! Thanks so much, I just couldn't remember the name of that game. How did you recall it from over half a century ago? Looking up used editions of WFF'N Proof on Amazon I recognize the instruction book published in 1965. That must have been around the time I received the game. It looks like more recent sets were more extensive. Well, the game likely had a positive influence on me, I ended up with a Math degree in college. Even in high school, I understood logic and proofs better than the other kids in my school.
