Buster Blackjack @ Sycuan, CA

Posted in blackjack sidebets by stephenhow on February 18, 2009

At my nearby Sycuan Casino, they offer a sidebet on some of their games called “Buster Blackjack”. It’s an optional “bonus” bet the player can place, up to the amount of his blackjack bet, and limited to $100. It’s a bet that the dealer will bust, and its paytable is based on the number of cards the dealer busts with.
I wrote a little recursive program to calculate the distribution of dealer busts for a 6-decks shoe, and worked in their paytable.

Dealer Bust Cards Payout Probability Return
3 2:1 1.73032e-01 0.346064
4 2:1 8.93918e-02 0.178784
5 4:1 2.04726e-02 0.081890
6 12:1 2.63760e-03 0.031651
7 50:1 2.14444e-04 0.010722
8 250:1 1.15280e-05 0.002882
no bust -1 0.714240 -0.714240
total 1.000000 -0.062247

So the bet has a typical bonus bet edge of 6.2%.  It’s a lot better than I thought it’d be.

    I get to play the fine East Coast Stand 17 variety of Span21 and have been very successful as I have gotten backed off only infrequently.

    The S17 variant of the game has a radically increased E O R (effect of removal) for the Ace.

    Posted in the wrong place.

    I hope that my pithy comment

    can be moved to the Spanish 21 thread !
