We had my young bloke's 6th birthday party not too long ago. It was pelting down rain pretty much the whole day and we ended up with close to 20 kids in my garage.
The machines saved me and kept the kids amused in between party games. It was sad to see that the veast majority of these kids had never even layed eyes on a pinball machine before. Kids being kids though, it didn't take them long to firgure it out after a few lessons from my kids.
This is my little pinball wizard back when he was 3.
