We don't have a Dave and Buster's around here, but we do have places like D&B's where they have the Deal or No Deal game. It's VERY addicting! As much as I've played it, I've never won the double-deal jackpot. (In some places, you'll get 400 tickets. I believe the double-deal jackpot is 600 tickets at King's Island, if I remember correctly.)
We have one of those in the food court of the local mall. It doesn't use tickets since it's a standalone machine, but it has a top prize of 1,000,000 tickets (2 mil for Double Deal), and you can collect the printouts and put them in the mail to collect prizes.
To give you an idea of the prize ratio, it's 1.5 million for a $10 gift card, 3 million for a $25 gift card, all the way up to 25 million for a GPS unit.
I love this game because...well, it's really, really easy to win. I always get a chuckle when I see someone playing the Stacker game next to it because, if you have an eye as quick as mine, it's quite possible to win the million at least half the time.
