From the instructions:
OBJECT OF THE GAME: To answer opera questions in six categories, then move your token to Valhalla for a chance to win the game."
My recap: One player rolls the die, moves his pawn and answers the appropriate opera question from a card read by his opponent.
Questions are in the following six categories:
Lives of Opera Composers
Female Singers
Male Singers (and a Few Conductors)
Music, Characters & Plots--Questions about the Opera
Opera Companies
The Media--Recordings, Quotes, Films, Plot Sources
If the question is answered correctly, the player rolls and moves again to another question. If answered incorrectly, play moves to the left.
To win, answer a question correctly in each of six categories, move to Valhalla by exact roll of the die, answer one last question in the category picked by the the opponents.
Sounds like Trivial Pursuit for the Opera buff.
Contains 6 pawns, one die, score pad, trivia cards, roll-up board and the rules.
