    6:5 single deck with great rules; house advantage?? Playable??

    Hello,

    I know 6:5 blackjack is a terrible game, but just curious if all the great rules make this a playable game?


    • Single deck
    • Double down on any first two cards
    • Double down after splits, except Aces
    • Split any pairs up to four times, except Aces
    • Take unlimited hits when splitting Aces
    • Surrender half your bet, original two cards only, after dealer checks for blackjack
    • Blackjack pays 6 to 5
    • Even money for insurance not allowed

    Using REKO with full single deck indices. Spread around 1-8. No positive on penetration. Just assume 75%...

    Thanks in advance... I know I need to buy CV Sim, just haven't pulled the trigger yet.

    It is my understanding that you would need a "piggish spread", something in the range of 40:1 to beat this game. 1:8 is not enough.

    Still a shit game despite all the add-on rules. 6:5 trumps all. you can find exact house edge at wizardofodds.com. There's a blackjack rule calculator there somewhere on the site.

    Thanks, I did't realize wizardofodds.com had such a great calculator. The 6:5 really kills it. I couldn't find if the game was S17 or H17, so I'm assuming it was H17. With 3:2 rules the game is +0.13 EV, with 6:5 it sinks to -1.26%. So the 6:5 is about -1.4 by itself. Not playable at all for me...

    Some 6:5 games can be beaten with card counting, barely. There are very good reasons to play 6:5 games if you have skills beyond card counting. These games offer little heat and an excellent EV relative to count games.

    Here is a post on 6;5 single deck. You need to good pen and a larger spread.

    At 75% pen, this is a great (monster) game. Run a CVData sim and you will see.

    The problem is finding that kind of pen on a SD game.
