I'm not at all leary of playing Indian Casinos at VP.
In fact, I've won more on SOME Oklahoma VP machines that I have out in Vegas. I mean, you could watch the little BINGO card on a VP machine and you would see that you were granted a win only when the numbers came up on the BINGO card! They now are allowing Class III VP machines that are not tied to the BINGO game and their payouts seem to be in line with those I play in Las Vegas. These machines (Class II in Oklahoma) were tied to some BINGO game and didn't necessarily seem to follow the expected payouts that a Class III machine would have. Until recently, Oklahoma had some law that did not allow class III machines such as are available in Nevada and other casinos around the country. The other 80% of the table's income is supposed to go back to the players in the form of drawings or tournament payouts. The casino gets only their per hand antes from the players as income. At least to the point of making sure that the Poker and Blackjack tables are paying them their 20% of the table's income. I believe that in Oklahoma, the Indian Casinos are regulated by the State.
