Also, I've read that in video poker, the draw cards are determined when you press "deal" the second time. In other words, if you draw four to a royal, the final card you receive is determined after you hold four cards, and then you press "deal."
That's what I do also. If I hit a big win I let the music play out. On women looked at me and said " why don't you just press the button and stop that noise" My response was that I paid a lot of money to hear it make that noise and I'm going to enjoy it for as long as I can.
