Yeah, one day, being at drinkery, I have been an art and part of jackpot on a fruit machine which was placed in the gambling area of that rum-hole. I was there with my girlfriend and to entertain her a bit I decided to teach her to play slot. I changed almost all my money to chips and tried many times  to trigger any winning combination by pulling slot handle, but all in vain.  Finally, when my pockets were almost free of those chips she asked me to try it herself and I gave her my last chips. And, lo and behold, she got jackpot. She got a lot of chips that were poured freely the box's inside. We cashed them out and divide it equally.

My girlfriend was the strategy-changer in that case.
