New Life Games Tech Forums

I am considering buying a Game King machine in the near future and I have looked thru all the posts in Game King and cannot find a clear definition of the different versions: 4.3 5 ect. and what the difference is between  different versions.

I do not care it the cabinet is super deluxe, just that it is clear screen and plays good.

The main game I am interested in is the Black Rino and I do not think it is in the 6.0 version. Also most of the machines I see for sale are coin less and they say you add credit thru script. What does that mean?

If I can get a clear understanding of the different versions, then I can narrow my search down.

Thanks for this great sight and the great people that help me.
