I had never seen or played a Zac machine ( in real life ) before Paul bought the Clown.
I have to admit that Robot was a fun game in the 30 minutes I spent on it ( I had to leave as Louise was not happy yesterday and kept making war signals in my direction  )

For those of us that enjoy pinball artwork , both the Zacs have wonderful colours on the playfield as well as the BG - especially the Clown BG 
Enjoyable games with some unique features.
