When we compare the rules of double-deck variations, we are going to use what I will term a, ‘ Control Game,’ and that control game will have the following rules: However, for the basic strategy player, double deck games offer fewer opportunities than single-deck games to make decisions based on the, ‘ Deck composition,’ and it is for that reason that double deck has a greater house edge. Even though it is dead wrong, there are still pit bosses out there who believe, ‘ A six (or eight) deck game cannot be counted.’ĭouble deck games, either way, certainly can be counted. Granted, all other things equal, the card counter will generally get more favorable opportunities against a lesser number of decks and will buck a lesser negative expected value while waiting for positive counts, (because fewer decks is generally good) but all other things are not equal and games considered, ‘ Highly countable,’ are often subject to greater scrutiny from the pit as well as the eye in the sky. In the case of card counting, multiple decks are something of a boon and a bane to card counters. In the event that all other rules are equal, then the more decks a Blackjack game has, the greater the House Edge will be against the player, which is to say that there will be a lesser return to player. As we have discussed before, the number of decks with which a Blackjack game is played is essentially a rule unto itself and impacts the House Edge of the game accordingly.
