I set the game up locally on my computer and am playing against the house.

I was able to double down after a split. It was 2 4's that I split. Problem A) Both hands were dealt at the same time, it's supposed to be one at a time it does matter and B) I hit a 2 and a 4 so I had a 10, the double down hand was not grayed out. I doubled down and got an Ace and it didn't let me play my second hand and just gave me the win

This script is very incomplete and riddled with logic and gameplay bugs it is not worth the 1.2BTC that was paid.
