Interplanetary Voyage

One of four add-on games released for the Odyssey in 1973, Interplanetary Voyage lets players pretend they are space pilots on missions throughout the solar system. It comes with game card #12.

Picking one of the mission cards, the goal is to land one's spaceship on the right planet. This can be achieved by giving the horizontal and vertical controls a short spin and hoping that the player spot will come to a halt in the correct location under the screen overlay.

Another mode of play called University of the Solar System makes use of the 72 included knowledge cards. These contain questions about the solar system which players have to answer, decoding the correct solutions on the game board.
