Here we have a beautiful example of Argosy, the last four-player EM from Williams.
This game is simple in concept but challenging in practice. Hit the four drop targets to score the lit value or light the saucer, which in turn lights the the extra ball lane and scores the special, when lit. The spinner lights alternately on 10 point switches and the small lane at the top opens the gate on the left outlane and scores 10k when the bonus is maxed out. Much more going on with this one than initially meets the eye.
