Zombie Blackjack Rules and House Edge
Zombie Blackjack can “box” some busted player bets and revive them if the dealer busts with 23 or more, but dealer 22 pushes or defeats key wagers. The full rule package can still carry a substantial house edge.
When a busted bet is boxed
Geoff Hall’s Zombie Blackjack uses conventional blackjack rules except for its stated changes. With a dealer upcard of 7, 8, 9, 10 or ace, a player bet that busts—including after doubling or splitting—is set aside or “boxed” instead of immediately collected.
If the dealer later busts with 23 or more, the boxed bet returns to life and wins even money. If the dealer reaches 22, the boxed bet loses.
Compare the variant with standard blackjack rules.
The push-22 trade-off
When the dealer busts with 22, non-busted player hands push except blackjack. The same 22 causes boxed bets to lose. This compensation rule is essential; “you can still win after busting” is only half the description.
Documented configuration
A documented field-trial version used six or eight decks, dealer hits soft 17, dealer peek, double on any initial two-card hand except after splitting aces, double after split, and no surrender. Blackjack could pay 3:2 or 6:5, and re-splitting aces was configurable.
Wizard of Odds estimated a 1.03% house edge for the Venetian configuration with 3:2 blackjack, eight decks and no re-splitting aces. Its reported effects were +0.07 percentage points of player return for re-splitting aces, +0.03 for six decks and -1.36 for changing blackjack to 6:5. These figures apply only to those assumptions.
Strategy must match the variant
The boxing rule changes decisions when the dealer shows 7 through ace, and deck count or ace-resplitting can add exceptions. Do not apply a standard chart or transfer the 1.03% figure to a different paytable.
