The game is totally different from the regular full casino, so it have to be developed more, i think it is still only 20% of the work done because in this process single game takes lot of time.
Part of why a single game takes some time (I think rougly 1:20 minute per round), is because it's meant as a simplified, social Blackjack game, where multiple people can bet on the same seat.
That's why the cards will keep dealing until all tables have 21, or bust, and then deal all the dealer cards.
Double-down is in the making, but because of the above Splitting is not possible.
We're working on more games, which include Private Seat Blackjack, where splitting will be available and the rounds will be much quicker as you can decide when the next cards will be drawn.
