Introduction

For all games except Craps, log files were made available to me by FTP for the period of July 1, 2002, to January 31, 2003. The Craps log files are based on data from 01-01 to 05-20-2003. Some files did not encompass this entire period of time, such as Blackjack, for example, due to the large file size. This report shall show on a game-by-game basis the results of my audit.

Baccarat

Following are the overall Baccarat results:

Following is the distribution of each card:

Following is the distribution of each card:

The next table shows the outcome of each hand, the theoretical probability (based on 6 decks), and the expected total based on the theoretical probabilities and the total sample size.

The result of a chi-squared test on this table is a probability of 0.515909678.

Blackjack

Following are the overall Blackjack results:

The next table shows the card distribution:

Next are the results of a chi-squared test on each distribution:

Craps

The initial Craps files I looked at from August 1, 2002, to January 1, 2003, showed an unusually high number of fives thrown on each die, although not enough to skew the odds by more than a negligible amount. However, data from January 1 to May 20, 2003, looks much better as follows:

This distribution has a chi-squared statistic of 2.864 with 5 degrees of freedom. The probability of a fair die producing a distribution this skewed or more is 0.720917. So these recent results are well within the normal range. The nature of the log files made it difficult to look at the entire game overall. However, I studied the result of player pass line bets.

The house edge over this sample is not far from the mathematical expectation of 1.41%. The percentage of winning pass line bets is 49.21%. The expected winning percentage is 49.29%, again very close to expectation.

Roulette

Following are the overall Roulette results:

The next table shows the frequency of each outcome:

A result of a chi-squared test on this distribution is a probability of 0.534021.

Caribbean Stud Poker

Following are the overall results for Caribbean Stud Poker:

The next table shows the card distribution:

The next table shows the results of a chi-squared test on each card distribution:

Following is the frequency of each poker hand, the theoretical probability, and the expected total based on the sample size:

A chi-squared test on the hand distribution above results in the following probabilities:

Slots

Following are the overall results for both types of slot machines:

Video Poker

Following are the overall outcomes of the three video poker games:

The next table shows the frequency each card occurred in each game:

The next table shows the results of a chi-squared test on each game:

Next, the poker value of the initial hand was scored in each game. In joker poker, hands with a joker were not scored. In deuces wild, the deuces were not considered wild. Following shows the distribution compared to statistical expectations:

A chi-squared test on the actual distribution results in a probability of 33.53%.
