Hope this helps -
One of my favorite adventures is Castle Amber X2 by TSR from the 80's. It has a number of clever puzzle type rooms including a meal that the pcs can join served by ghosts. Each item of food gives a different effect - some helpful and some harmful.
Also - I just purchased "Temple of Mysteries by Monte Cook from RPGdriveby. It is a puzzle/riddle/trap based adventure.
Finally - I am itching to buy some books from Cloudkingdom. They publish books with puzzles/riddles for adventures.
Thanks for the great ideas everyone - I copied several down and will use them to torture my family - lol.
