Like any other game Multi-hand Blackjack has certain rules. 

This version of Blackjack is played with 5 decks of 52 cards each, which are shuffled after the completion of every game.

You may draw up to five additional cards on each hand (i.e. a total of 7 cards), as long as the value of your hand does not exceed 21. If you go over 21 this is called a bust and you automatically lose that hand. If you have not yet exceeded 21 after receiving seven cards you will automatically stay and will go onto your next hand or the Dealer will play his hand. 

The Dealer must stand on all 17 and draw on 16. 

All face cards - Kings, Queens and Jacks, have a value of ten in Blackjack.

An Ace card may have a value of either 1 or 11. Any combination of cards that contains an Ace and whose value does not exceed 21 is referred to as a ‘soft hand’. An Ace will adopt the value most beneficial for your hand. For example, an Ace and eight will add up to 19, but if you choose to take another card that would cause the hand's value to exceed 21 the Ace will revert to a value of 1.

If you are dealt an Ace and a card with the value of ten as your first two cards this is called Blackjack. You will automatically stay when you receive a Blackjack and move onto your next hand. If you beat the Dealer with a Blackjack you are paid out at 3 to 2. 

If the Dealer gets Blackjack your entire wager (both original and Double or Split amounts) is lost.

If you receive two cards of the same value, such as two Ace’s or two Fives, you may Split your hand. This means that your pair is divided into two separate hands. You wager a second amount equal to that of your original wager on the second hand. You then continue to play both as separate hands, however once you have split you cannot Double on either one of those hands. 

Cards of the same value but not of the same denomination cannot be split in this version of Blackjack. So while a king and ten may have the same numerical value a hand consisting of these two cards cannot be split because the cards do not have the same denomination. 

If you have Split a pair of Aces and then draw a card with a value of ten then this is NOT counted as Blackjack. Such a hand would have a value of 21. It will beat any Dealer's hand with a value of less than 21 and draw against all other Dealer hands except a Blackjack. This rule also applies to splitting pairs of cards with a value of ten. Should you split a pair of tens (or face cards) and then receive an Ace this hand is not counted as Blackjack.

If the value of your initial two cards on any of your hands is 9, 10 or 11 then you are allowed to Double. This is a wager that your next card will be sufficient to beat the Dealer’s as-of-yet-uncompleted hand. This wager costs as much as your original bet for that hand, but should you win you will be paid double your total wager on that hand.

Insurance only covers your original bet. It does not cover any Double Down bet. When the Dealer is dealt an Ace you are given the option to place an insurance bet. The Insurance bet costs half your original bet and will pay out 2 to 1 if the Dealer gets Blackjack, however, you loose your original bet. If the Dealer does not get Blackjack you lose your insurance bet and the game proceeds as normal.

After all hands have been played, your hands are compared to the Dealer's hand. If the value of both hands is the same it is called a Push. In the event of a Push you receive your bet amount back and no one wins. Blackjack (which value is 21) beats a hand that's value is also 21. If both you and the Dealer have Blackjack this is considered a Push.

Please Note - This version of Blackjack is played with 5 decks of 52 cards, which is shuffled after the completion of every game.
