Blackjack rule guide

Six-deck H17 blackjack

When the dealer hits soft 17, the dealer improves some hands and busts others; the net effect favors the house.

Bottom line: Compare complete packages: a good H17 game can still beat a poor S17 game if other rules differ.

Reference package

With 3:2 blackjack, DAS, no surrender, dealer peek, and the shared split assumptions, the cut-card house edge is 0.63873%. Adding late surrender lowers the matched profile to 0.55051%.

Strategy changes

H17 changes several borderline doubles and surrender decisions. On the site chart, choose H17 first and then match DAS and surrender.

Table check

  • H17 costs about 0.21 percentage point in the matched six-deck profiles
  • Late surrender partially offsets that cost
  • Never infer strategy from the payout placard alone
