How Blackjack Rules Change the House Edge
See how common blackjack rules such as 6:5 payouts, H17, DAS and surrender can change the game compared with a stated baseline.
A rule effect is a comparison, not a universal house-edge figure. Always read the baseline rules beside the number.
Start with the human question
The useful question is not “what is blackjack’s house edge?” but “which exact rules apply at this table, and how do they change the game?”
What the numbers mean
The values are approximate marginal percentage-point effects versus a stated comparison. A +1.39 point entry for 6:5 describes the cost of that payout change relative to 3:2; it is not the total house edge of every 6:5 table.
Do not simply add every row
Rules and strategy assumptions interact. Use the dataset to screen tables and understand direction/magnitude, then use a complete ruleset analysis when precision matters.
