Hi. The key to any machine is learn the shots and the rules.
So play them all, and Google or YouTube the rules to study the best scoring strategy.
Virtual pinball is also fine for learning the rules. But it is not the same as real pinball. Also every real pinball machine plays just a little bit different.
You could have 2 of the same pins side by side and they won't be exactly the same. So you just gotta play them.
