Had two of them linked in my gameroom for about a year. Different rules (timed game with halftime), see each other's scores on both displays...fun when others were over. But I have limited space, so brought the linked pair to the PATZ show a couple years ago so everyone there could enjoy them linked. Ended up selling both to a couple guys there.

Lots of people do not like the game, but I enjoyed it....nice implementation of the theme. Linked machines were a lot of fun...and even a third way to play! Start a game at midnight, and it goes into Midnight Madness mode.
