This is my second Pachinko machine and one thing I noticed is that the payout percentage is too high. If I start with 30 balls it's almost impossible to lose them. I get too many jackpots.

I have read that I can adjust the nails and I'm going to look into that but I'm wondering what your experience is as far as payout percentage. Also how much does skill play into it? The only strategy I'm aware of is to try to shoot the balls more toward the center. Shooting the balls quickly so a lot are on the playing field at the same time also seems to increase the percentage but this might be an illusion.

Thoughts?
