I was impressed by the online casinos using real dealers and those scannable oversized cards. I don’t think I would have gone that route but great that people are employed and I guess that puts to bed any discussion about algorithms or if the computer is dealing under to itself. Wizard Of Odds is an amazing guy, I love the articles on his site.
The Wizard of Odds has a very thorough walk-through of the variations of rules - and what they mean to the odds:

Brings back memories from playing many, many hours of playing optimal strategy blackjack to release generous bonuses from online casinos. :)
Well done on launching btw. I second the UI suggestions about making UI a bit easier.
