Most of the rule effects used in this blackjack house edge calculator have been derived using data from Peter Griffin’s Theory of Blackjack and Arnold Snyder’s definition of the standard Vegas rules for the game.

 

Rule variations are applied to the base standard game and are either advantageous, disadvantageous, or neutral to the player (neutral rules result in a 0% house advantage). Advantageous blackjack rules are surrender, doubling after splitting allowed, presplitting aces allowed, etc. Disadvantageous blackjack rules usually limit the player’s options and include doubling down on 10-11 only, no resplits, no surrender, etc.

 

The casino will always have a slight edge (represented by a negative %). The trick to winning at blackjack is to minimize that house edge. To help you find casinos that offer the most advantageous rules, be sure to visit our Casino Blackjack Rules & Conditions page.
