I'm not that good, but I am getting better. I hang around for those occasional killer balls that make the adrenaline rush.
For some strange reason, I think I will go broke dropping quarters into and arcade machine, but have no problem with spending thousands just to save a few quarters
Seriously, I am getting better and get some lucky games in once in awhile. But as the others talk up, it is all about having fun. Enjoy them. Have gun playing them. But keep your eyes and brain open on how the shot is made. Case in point: Most of the highly needed shots are made at the very tip of the flipper; A few need to be backhand shots. But most are at the tip of the flipper.
You have to work on your reflexes. Especially your hand/eye coordination.
But have fun first.
