Blackjack actions have different names in game terminology. If you wish to receive another card, you ‘Hit’. You can continue ‘Hitting’ until you reach your desired hand total, or until you bust, whichever one comes first. ‘Splitting’ is available only with pairs. You ‘Split’ a pair of 4s for example. When you ‘Split’ you start playing two separate hands simultaneously. The rules for ‘Splitting’ will vary according to each Blackjack variant or casino. When you ‘Double’, you double your bet and take one final card. Whatever the outcome of that card is your final hand tally. You cannot hit after ‘Doubling’.
