Le mystère des pyramides (1990)

It is one of the Milton Bradley "Flipsiders" games that resembles an audio cassette until you "flip" the game open. The archaeologist takes the green marker and begins at the entrance to the pyramid. The other player, the mummy, begins at the bottom of the pyramid. A ruby is set in another room at the bottom of the pyramid. The archaeologist will get the ruby and back out of the pyramid. The mummy has to kill the archaeologist.
