My thoughts - let them struggle a bit. Like when Jessica first came over, I would let her play on default settings - and she would struggle and get frustrated. Now, before she got so frustrated that she burned out on the games, I'd ask her what was wrong and what was it that was frustrating her. She'd explain the situation to me, and I'd show her some very good starter points.
For example, she did not know about cradling the ball. I showed her that, and I explained to her that now you can re-focus, relax, think things through, and if you want to try for it - line up a shot with that flipper now. I told her first just cradle until she got the hang of it. From there, I told her, ok now try to go for "this" shot or "that" shot. She'd struggle for a bit, but then she'd get the shot. THEN I showed her, "hey....see the artwork on the playfield - notice how THIS part of the artwork was kinda like an indicator for where the ball will go if you hit the ball with the flipper at this moment....isn't that easier than cradling and trying to aim by eye..." - once she saw that, she started getting really good - and way more importantly - she started enjoying herself.
Another good example of helping her along was showing her the in-lanes, and how lighting up all 3 would give her some kind of multiplier. Or with DE games, I'd explain to her how to get the skill shot when first launching the ball, or how to get the skill shot on games like MM or AFM. Those lil' achievements and learning some easy points can be satisfying and boost one's confidence.
I like to think there's a reason why WAY more men participate in things like cars and pinball - women love to play too - sometimes they just need a lil' guidance/direction. Like Jessica, she loves to participate in some things that I like; she just does really well when someone holds her hand and gives her some confidence. There's a fine line between giving her confidence and micro-managing her every single move and shot on a pin, and sometimes - I purposefully let her struggle until she asks for help, or I let her "try to fly" and she soars.
Proof is in the photograph - she nailed Cryptjam on TFTC.
