GotG Pro is my first pin and I've got a ton of games on it already, but would like to know if there is any sort of detailed rule sheet for it. Specifically I'm curious about how the Sanctuary mode works as I seem to complete that mode without making any shots until after the timer has expired.
As for my enjoyment of the game, I think it's been fantastic so far. I did try a few games on the original code before upgrading it and can see why some people were frustrated with it, but on the latest code it has been a lot of fun.
