You may raise the bet from $0 to $40 after each card is drawn.
When you are done drawing cards, click [Yes], then the "Dealer" selects cards
from the deck based on Black Jack/21 rules (the dealer must beat your cards or bust, but
the dealer wins in the event of a tie). The [Shuffle Deck] button need not be pressed every game since it can be fun to
try and remember which cards have been played and adjust the
probabilities accordingly, which the
"dealer" can not do. The cards already dealt in previous games are put back in the deck in original sequence.
If the cards in the deck are all dealt, then the sequence of cards begins from the start again.
The [Probability of Bust] button can be clicked to see what the probability of busting (getting
over 21) if another card is drawn. A probability over 0.5 means that you should think twice about
taking another card.
