Sports games:
Be A Nascar Driver, Hockey Fantasy Pool, Title Race, Drafted to the Predators, Hockey History: Do You Know Your Hockey?, Hockey Quiz- Vancouver Canucks, Hockey Quiz- What NHL Player are you?, Quiz- Kansas City Royals
Some of these are in quizzes, some are in fan fiction, some are in everything else.
IMO- the issue with Mystery/Puzzle vs. Mystery/Horror is that mystery and puzzle don't necessarily go together. The "maze" type games I would call puzzle games. Same thing with 8 goals and Twenty-three. (Also, to some extent, The Tapestry, I suppose.)
