Gambling for kids

This is a typical game at kid oriented restaurants. You start the light spinning and then you push a button to stop it (of course the place it actually stops is random). Where the light lands is a number, and you get this amount of tickets redeemable for prizes. Most spaces give you 2 or 3 tickets. There is one space that gives you 500 tickets.

Other than the fact that the normal suggestively dressed women have been replaced with a goofy mouse, how is this any different than a slot machine?

These games have a significant effect on my daughter. I see the adrenaline kick in on her face when the big payout spins by, and I see the impulsive need for her to play one more time (repeatedly), particularly when she feels she almost won (which happens a statistically improbable number of times).

I let my daughter play these games, but I turn them into an economics lesson (it isn't easy being my daughter). We did calculate how much she spent to get a prize, and the looked up the actual price of the price of the prize.

Does anyone else have this reaction to these games? How do you handle them with your children? My daughter points out (in her very articulate manner) that it is just a game.... but it still seems a little inappropriate to have this type of machine marketed to kids for same reason that it is wrong to sell kids scratch tickets.
