Great, but gets boring too quickly.
This game is already good at it's state, a traditional Black Jack card game. Some people might vote lower, because there are already black jack games on Newgrounds, so some might consider it "unoriginal".
For example, there are countless "Snake" games on NG, so most decide to blam, because it is just the same thing.
However, some snake games are special, for having extra elements.
For this, try to add different elements to the game, but I can't help you there, I don't have expertise in flash, or AS...
Kudos to you.
Good job on a great, classical game.
3/5
