Yep - that was the skill on a lot of 6 digit machines - Meteor and Galaxy come to mind.  It was considered very poor form to spank the high score on these games after they were reset - work it up to 999,990 as slowly as possible   The interesting thing on my Paragon is that it pays the replay scores the second time around after rolling   Not sure if I have the latest ROM revision in it.

I have now converted my Meteor to 7 digits, which solves the problem, but I don't think anyone has done the software for Gorgar.
