The first is the roll dice which I also dislike.
The second is to allow the player as many guesses as they have an int modifier (thus the intelligent character has a better chance).
Third, allow the role to give an additional clue
Fourth pay the consequences of not being able to answer (ie attacked).
Riddles I feel shouldn't be used as a central plot device, rather more a way of unlocking 'extras'. ie you don't have to answer the riddle to solve the problem at hand, but doing so might mean you gain a special bonus.
