One of the software developers of online casino games is being challenged by maths experts this week. An odds expert claimed that "It would be 184 times easier to win the Powerball 2 out of 2 times than to be as unlucky as I was in this craps game." The company behind the games is software developer BLR Technologies which is based in Costa-Rica. Player allegations that its online craps game is hopelessly rigged have been confirmed by odds and statistical experts have confirmed.

Mike Shackleford and Jacobson Gaming’s Eliot Jacobson, both highly respected professionals in the calculation of odds and probabilities have concluded that the BLR craps game is definitely not fair to players.

Shackleford claims on his website “I first became aware of the allegation that online casinos using BLR Technologies software were not playing fairly in craps when a member named clempops4 posted a complaint on my forum on October 28, 2011. At first, the member claimed to have won 25% only out of 3,200 bets made. However, the member didn't say what he bet on. Thus, I was not immediately impressed with his case.

Shackleford then goes on to explain how he has come to the conclusion that the casino games are rigged and that players should avoid any site using the software:

“The "chi-squared goodness of fit test" is useful to compare actual to expected results with data such as this where there are multiple possible outcomes. In this case, the chi-squared statistic is 89.61 with 13 degrees of freedom. The probability of results this far from expectations or more is 1 in 6,036,452,793,441.

What was even more striking is that in every way I could have won, my results were less than expected, while in every way I could have lost, they were more. Following are my overall win/loss results:

Wins = 81

Losses = 247

That is a win rate of 24.70%. The fair probability of winning a pass line bets is 49.29%. Could it just be bad luck? Let's see...

• The standard deviation on the number of wins in 328 rolls is 9.054.

• The expected number of wins in 328 rolls is 161.681

• Actual wins was 81

• Deficit in wins is 80.681

• Number of standard deviations south of expectations is 80.681/9.054 = 8.911.

• The probability of being 8.911 standard deviations or more south of expectations is 1 in 3,940,183,270,432,190,000.

To put that in perspective, the odds of winning the Powerball Lottery are 1 in 146,107,962. It would be 184 times easier to win the Powerball 2 out of 2 times than to be as unlucky as I was in this craps game.”

Shackleford also explains how he is not the only expert that has come to this conclusion:

“In addition, Dr. Eliot Jacobson performed his own tests. His results were even more unlikely than mine.”

Because of the extreme bias in the results I obtained, as well as the consistent bias documented by others, I am warning players against playing at any casino using BLR Technologies software, especially in craps.”

With the growing media attention the issue is raising at least one operator has decided to already dump the software

"With the present accusations and facts against the BLR casino platform, the 5Dimes group has chosen to remove this casino platform from our multiple casino lineup.

"BLR was given ample time to address the concerns of forum members as well as our direct questions. No acceptable answers were given, so the casino platform was removed.

"A management decision was made to eliminate that casino and focus on expanded offerings with the other casino platforms."

BLR Technologies offers a gaming platform featuring sports and casino software. The casino client enables any interface which supports XML Communication including smart phones.
