Tool
Blackjack Rule Comparison Calculator
Compare how selected blackjack rule changes can affect the game relative to a stated baseline.
Quick answer
Use this calculator to compare rule effects, not to assume every blackjack table has the same starting house edge.
What the estimate means
The output is the approximate change in house edge relative to a 3:2, S17, DAS game without surrender or resplitting aces. It is useful for comparing rule importance, not certifying a table return.
Why 6:5 dominates the comparison
The approximate 1.39-point penalty is much larger than the effects of H17, no DAS, late surrender or resplitting aces individually.
Use exact rules for exact math
For publication-grade house-edge calculations, record deck count, payout, soft-17 rule, doubling rules, split rules, surrender and dealer procedure.
