So there are casinos that have chips. I don't recommend playing Blackjack in Oklahoma, they start out making you pay to play a hand of blackjack (around 50 cents per $5.00 hand).

The class II gaming machines look almost like normal maching except you "daub" instead of spin. Daub is a bingo term so what the slot machine is doing is playing bingo in the backgroud to determine your win or loss.

I think some of the the casinos have moved to class III machines in the last few months. I was playing Video Poker (8/5) and some of the newer machines last weekend.
