If you have read our positive variations in house edge section you will know there are plenty of rules that casinos can and do add to their Blackjack games that will lower the house edge of that game.

Now as a player you want a lower house edge rather than an increased one so this section will alert you to all the rules that give you a worse game by virtue of an increased house edge. As in the section mentioned above these rule variations and increases in house edge are based on one particular game which is available in most casinos.

This Blackjack variant is one that uses eight full decks of playing cards and where the Dealer always hits a soft 17, and one where a player can double down on the first two cards dealt, and also after the cards have been split, and which also let you split to make a total of 4 separate hands.

We should alert you to three rules that does not affect the house edge on the game mentioned above and these are Late Surrender against a Dealers Ace, or when a player is forced to stop playing his hand when he reaches 6 cards in total or when Late Surrender is offered after splitting.

Now if the game rules say you can split a hand to a maximum of just two hands, then the house edge is increased by 0.01%. If no peek is in play with an Ace then the house edge increases by 0.01%.

Sometimes the players cards are dealt from a separate shoe than the Dealers cards, when this is done the house edge increases by 0.06%. If you can only double down with a ninw, a ten, or an eleven then the house edge increases by 0.09%.

If a Player may not resplit his cards then the house edge increases by 0.10%. If you are playing European Blackjack with no hole card then you can expect the house edge to be increased by 0.11%.

If the rules say that a player may not double after splitting, then this will increase the House Edge by 0.14%, or if you can only double on a 10 or 11 only then this will result in the house edge increasing by 0.18%.

If you cannot split Aces the house edge will be increased by 0.18% and if a Blackjack pays 7-5 then the house edge increases by 0.45%, a Blackjack that pays 6-5 then the house edge increases by 1.39%

Player loses 17 ties will mean the house edge is increased by 1.87% and should a Blackjacks pay Even money then the house edge jumps by 2.27%.

If the rules state that a player loses 17 and 18 ties the house edge increases by 3.58%, if players lose 17, 18 or 19 ties the house edge will be increased by 5.30%, even worse if players lose 17, 18, 19 or 20 ties as this increase is 8.38%.

Finally the worse two increases in house edge happen when the rules state that a player will lose ties of 17, 18, 19, 20 or 21, the increase in house edge due to this rule is 8.86%. If a Dealer bust on 22 is classed as a push then the house edge increase is a disgusting 9.53%!
