Also, I ran my simulator on 1 million plays, and show the average payout over each 10k plays. It seems to suggest the true house edge is more like 4.25%:

Nice analysis! I do plan on lowering the house edge. 4% seems too high relative to other games. I will post to this thread when completed. I might add a special slice on the wheel that is a mega-jackpot (10x or 20x). That will give me an easy parameter to tweak in order to adjust the expected value.
