A few weekends ago, we had a couple of birthday parties to go to. One of them was at The Jungle and the other was at Chuck E Cheese's. Both of these places have games that the kids can play and get tickets that can be redeemed for cheap toys.
The funny think about these places is that it reminds me of Vegas. Seeing these kids walking walking around with cups filled with tokens or tickets.
I am sure that the companies that makes slot machines also make these video games. I am sure that they want kids getting into these games, so they will feel comfortable with slot machines.
