Brain Wave , an educational game for the Magnavox Odyssey, was released in 1973. The goal of the game is to build a "train of thought" across the game board by blocking your opponent's path. The thought tiles required for this can be bought using points earned during the on-screen part of the game.
The gameplay involves two main parts: the on-screen part and the game board. On the screen, players take turns rolling dice to decide how many fields they can move their spot through a maze. The attacking player then tries to serve the ball with such a trajectory that it hits the defender, while also considering the points earned from the thought tiles.
