Oklahoma does have Class III gaming machines. Many casinos also still have Class II machines. These bingo based machines have an electronic video bingo card on the front of the machine and you can usually choose different cards while playing to get into different bingo games.
Profits from class III machines generally have to be shared with state or local government, hence the tribes were slow to roll them out.
.25 8/5 JOB and $1 8/6 JOB are usually the best paytable you can find, these paytables are comparable to the Kansas and Missouri casinos. There are Class II and Class III video poker machines. Gameking multiplay games are the most common in my experince.
Craps and Roulette are card based if offered. I was told the reason for the ante is that these games are self financed ( in other words, your losses at the table go into a pool to pay for your wins at the table ) and the ante is where the indians make their profit.
So please do come to Oklahoma, we need the revenue !
