Apart from the rules that apply when a dealer busts with 4+ cards and the other special rules, you can play the game like in other blackjack versions.
As for strategies, you should search out a new mega blackjack strategy chart to help with a game plan. A strategy gives possible ways to effectively respond based on the card value on your hand and the dealer's face-up card.
