They’re at the Post (1975) https://boardgamegeek.com/boardgame/2041/theyre-post A horse racing game on vinyl that produced different outcomes based on which concentric groove the needle ended up placed on.
Only saw it being played once or twice as a kid and it has stuck in my head ever since. I should try to pick up a copy.
@scronide Wow, the game design for that number of outcomes is really pretty impressive.
