Last week, I glossed over the cost of playing less than full-pay machines.  This week, I'm going to jump into this topic a bit further.  Full-pay machines are the version of a particular type of video poker that have the commonly found highest paybacks.  The obvious example of this is what is called the 9-6 full pay jacks or better machine.  We call it 9-6 because this is the payout for the Full House and Flush.  What about the other pays?  Well since the bottom 4 pays are usually 4-3-2-1, we don't see much variation in these payouts.  Lowering any one of them would require an identical payout for two hands of different ranks.  Casinos try to avoid this where possible.
