Just got my first pachinko a few weeks ago. First one I have played in over 25 years. Decided to go with Popeye for my young kids to enjoy. Beautiful machine as a whole. I do have a question/ concern so I am coming to the experts for help First few days into playing I got into the bonus round a couple of times. On one of those occassions, I ran out of balls and did not realize it. When I went to play it again by adding balls, the ball release would stay open and I was forced to reset the machine and was ready for normal play again. Since that reset, I have played over and over again(more than 5000 balls) and have not gotten a bonus game. Is this a normal thing? I also have noticed that on the bottom left of the LCD screen there is always a negative sign blinking. Don't know what that means. Anyone can provide some feedback? Thanks
