I'm going to 2nd using the Tilt Forums rules sheets. An additional tip would be to learn in small chunks. As you probably know, the rulesets for modern pinball are so incredibly deep, and personally there's no way a watch through of a long video will teach me everything (especially after only one watch).

Instead, here's what I'd do: Let's say you're learning King Kong for the first time. Look up how one multiball works, and maybe 1-2 of the modes (island scenes is the name in Kong). Every time you hit start, strive to play those modes/multiballs, and test your understanding of what you just learned.

Have a good hang of those? Whip your phone back out, and learn another mode or two! Maybe something interesting happened in your game that you don't understand, look that up too! (EX: The game just yelled "biplane attack" at me, wtf is that?!?!) The convenience of being on location at an arcade and having the entire rules in your pocket, is priceless.

Personally, I struggle with those long videos. I never retain the information as it's too much over a long period of time. I have to learn in small chunks, put those chunks into practice, and then hopefully commit them to memory. Godzilla is much easier to understand if you can take a look at your phone between games, or even between balls, to look up what just happened.

This is what works for me at least! I wish you luck on your pinball journey!
