One to four players can play. If only one plays, horses 2,3&4 move a random length each time player #1 shoots a ball. First horse to the end wins, if two tie winner goes to highest score. There is a picture of the play field at the top of the post. All four are identical except #1 has a rollover switch at the bottom of the channel where the ball is shot from, this motions the other horses to run in a one player game. If two or three people play , they play against each other and the unused horses just sit there.
I did get the coin acceptor to work, there was a great how to on this forum , very simple if you see one broke down. I can not figure out how to mount it to the bezel and align the return slot up on the door.
