It could be as simple as the tickets could be swapped for crap at the counter or credit back on the Time Zone card which you can then reuse for more games, teenagers and adults would go for that I am sure. The pinnie could be set for a free game on match and get to certain set points or every 20 million gets you a ticket worth 20 cents credit.

Timezone could have a permanent platform for a 1 or 2 pins for kids only to entice them to play. I don't think kids would understand the rules as long as they can see the ball go around and bash it.
