New Card Craps Practice Game

Posted in +EV, card craps, csm by stephenhow on February 21, 2011

The best way to understand counting for card craps is to see it in action. I wrote a new practice game to demonstrate counting against the point, and when it’s correct to lay odds with your Don’t Pass bet. The game is configured with the Viejas parameters (10x odds, 312 cards in a ShuffleMaster 128 CSM) so if you’re planning to check out the game, practice here first! Sometimes I just like watching the rolls, so I also included an “Auto” mode to continuously play by itself. This might give you an idea of session variance, and what to expect if you actually decide to play 10x odds.

I like watching all the animation and highlighting. It’s a lot more fun to run the game in a browser window, and occasionally see how it’s doing, than it is to sit and grind it out at Viejas all day πŸ™‚

    do you give up a lot if you use a 3 roll window as opposed to a 6 roll window?

      The simulator shows a +2.7% edge for a 6-roll window, and a +2.2% edge for a 3-roll window. So I guess you’re giving up 0.5% for using a strict 3-roll window vs. a 6-roll window. However, you’ll find it’s easy to track the 4/10 and 6/8 counts for more than a 3-roll window. Usually, my 5/9 counts are pretty inaccurate at the start of the point, but improves as the roll goes on.

    Shouldn’t it be $85 total bet on the 5 and 9 with odds (it shows $80 in the game)

    Nope, you are right, I am mistaken. ($80 is correct). Sorry about that.

      No problem! Thanks for checking out the game.

    Thanks! If one bets the “Don’t Come” after the Dont Pass would it increase the winrate without increasing the variance too much. (Would it be almost like playing two tables at the same time) but it should also double the winrate?

      You’d increase the win per roll tremendously if you play DC every roll. However, it’s hard to track all the points without writing down the rolls. You’d also drive the dealers crazy by putting up and taking down the odds on the DC bets. You’re better off sticking to the DP line, which is “self-service”.

    I am down over 6.5K on the simulation. Tough game!

    • stephenhow said, on February 22, 2011 at 9:00 pm

      Yeah, the variance is crazy. My analysis says there’s still a 7.5% chance of busting out your $10k bankroll. You’ve really got to be committed if you want to grind the game out for it’s EV.

    Viejas is trying to become more consumer friendly. The dealers are the best. They have actually hired some pit bosses, who know how to treat a dealer mistake correctly, and to be courteous to all players. I could tell Maryann was from the Midwest by her natural charm. Keep trying Viejas you are getting there
