This is a very old, battery-operated electronic baseball game in which players try to outguess each other. The board depicts a baseball field dotted with lights that give the results of a play. The players use switches located at either end of the board for each pitch. For example, if the player batting presses the #2 button, and the player in the field presses the #4 button, the Strike lamp would light up, while a combination of #6 and #4 would result in the triple lamp lighting. Each player also has A and B switches that are pressed to light the Safe or Out lamps needed for the results of some plays (like if a runner tries to steal 2nd base). Wooden cubes are used to represent base runners. The player with the most runs scored at the end of 9 innings wins. Extra innings are played if needed. - BoardGameGeek
