Quoted from Euchrid:
I have had this discussion before here and some disagree, but - there is no luck in pinball. The skill shot on RZ is entirely dependent on factors such as slope of game, speed of plunge, friction coefficient of playfield, etc, but not one element of "luck" or "randomness". Why do many relate difficult shots or complex algorithms to randomness or luck? There are no such things.
I try to refrain from this but I can't resist:
lol- cmon dude- no matter what you think, the luck is in the MINUTIA of details
at an atomic level. Now Is luck a big part? not typically, depends on the game! Magnets in modern pinball operate on chaos theory, not a player's control or understanding of the table. Sparky, Magneto, Tron disc, etc can throw the ball wherever and whenever it wants. Avoid magnets? sure, just not fun and fun is the point.
The gravity, weather patterns, tectonic plate activity, etc etc are all impacting the slope, friction, character of the wood or coating, impacting the switches, impacting the springs etc etc. Pro's do a better job of maximizing accuracy and control on varying games and in varying environments. They adapt quicker and are able to repeat the portions of play which are "controllable". But no game I've ever seen has allowed the player to have 100% control, otherwise I believe some pro would still be playing the same game they started a couple years ago. The ball is designed to go in the drain.
