[TOMT] [Movie/possibly TV episode] [1990s] A woman plays a game possibly called "knack the atom" tha

[froodle]

Hi, TOMT. For years, I've been trying to find what I believe was some type of sci-fi movie or TV episode that I believe I saw as a kid sometime in the USA in the 1990s, but have never had any luck with Googling and the like. My memory is fuzzy and I'm surely misremembering details by now, and getting some things just completely wrong, but I'll try to describe the image in my head the best I can as a starting place.

The setting is some type of featureless void. A woman is walking through it, and comes upon an impish, perhaps not-entirely-human boy huddled over, eating a squirrel or a rat or something like that raw, with blood smeared on his mouth. They speak, and he invites her to play a game that I think he called "knack the atom," or "knock the atom," or something like that. He tells her that if she gets it wrong, the universe may be destroyed, and he hands her something like clear blocks or shapes with which to play the game.

Does this sound familiar to anyone? I'm fairly certain that this was something I saw on TV, and wasn't a dream or the like. I wasn't creative enough to imagine something like this anyways, haha. Thanks in advance!

machstem: Probably not what it is, but for some reason you brought up the memory of Eerie Indiana

I'll check some episode descriptions for that, but I don't think this was from a show aimed at children. I could be wrong, though.

HerbertWest: Eerie Indiana was and is a really underrated show! I rewatched it recently, and it holds up, unlike a lot of other shows that old.
