Pinball needs to cater a little more to ticket munching rugrats. Suggestions of audio blasting advertising "YOU WIN 50 TICKETS" Or other like gimmicks will help, but perhaps half size pinball legs for the kiddies which I have helped for a customer of mine and his handicapped kid or collectable cards and pogs like in ELAUT's Wizard Of OZ machines. I was at an amusement park and watched $300 get sunk in those machines in less than an hour on a weekday. I asked the op how much those machines were and he said 27K, but they were paid off in less than a month! Image for reference below. I am sure with all the licensed machines it would not be hard to create/install a dispensers much like slugfest or Initial D type video games with custom cards to be installed.
