Below is a list of rules variations you'll find on the tables:

1. Dealer Stands on Hard 17-- This is the standard rule of blackjack where the dealer will stand as soon as his/her score reaches 17 or above.

2. Dealer Stands on Soft 17-- The dealer stands on 17 or better even with an ace in the hand.

3. Dealer Hits on Soft 17-- This rule requires the dealer to draw another card if hes holding a soft 17 but will stand on a hard 17.

4. Doubling-- Some tables do not allow doubling, while others allow it. Some tables only allow doubling on the first two cards, while others allow doubling on any number of cards.

5. Doubling After Split-- allows you to double even after the hands have been split.  Some tables will allow you to keep splitting, as long as you keep getting pairs on the initial hand.

6. Surrender-- Can be “early” or “late” if allowed. You can “early” surrender before the dealer checks for Blackjack.  “Late” surrender is after the initial check. If you surrender, you retain half of your original bet.

7. Insurance-- if the dealer's up-card is an Ace, you will be offered “insurance”. This is a side bet of half your original bet. The dealer will then check the hole card to see if it is a 10 value. If the dealer does have a blackjack then insurance bets are paid out at 2:1. You will lose your original bet unless you  have a blackjack so the net effect is that youll break even. If the dealer does not have blackjack, youll lose the insurance bet and still have to play out your original hand.
