Common issue in the online backgammon world is whether or not the computer generated dice outcomes are true random or been manipulated by the servers.
While in offline backgammon players roll the dices on the board and supervise the process closely, in online backgammon games the players cannot see how the server generates the numbers, which can make them suspicious of the reliability of the dice results, particularly when they run into bad luck.
There has never been any kind of indication for unfair dice outcomes, other than pure luck.
In most online backgammon sites there is a use of the same random number generator, which is a certified piece of code and in fact has tested infinite times and approved by several external institutions. And on any of the attempts to check the credibility it had been proven without any doubt that the dice on all online backgammon is strictly random and fair.
In addition, most of the online backgammon servers received a certification from an Autonomous source which verifies the pure Authenticity and Coincidence of their number generator software. And above all there are many players, who perform an exact analysis of their games results, not to find and review their errors alone, but mainly to check if the dice has been fair.
Why am I so sure of the fact that the dice outcomes in online backgammon are pure?
Mostly because I myself have a long terms documentation of analysed match results, from almost any online backgammon site there is, which some contain over 1 million consecutive rolls from my matches.
The problem with this issue is that there are still differences of opinions regarding the dice random and the rumors about manipulations don't disappear completely. So, no matter if it is game for real money, competitive tournaments, or just for fun, there will be people who still suspect the outcomes as been manipulative.
Furthermore there is even a wide range of rumors, such as players using a dice program which allows them to control the dice and up to programmers accused of manipulating the entire software.
In general, most people remember more of the moments they run out with bad luck and the impression of those times is much stronger than when they win, and that is why even if luck has 50/50 chance, players sometimes might feel as there is something wrong.
Despite all proof and with as many arguments in favour of the dices random outcomes, someone who has had the impression that something is wrong ,will refuse to believe even the most solid one. They will state that "there seem to be too many doubles", for instance and if been shown with an analysis which proves that the results are not been fixed they would probably say that "there are still too many doubles on the wrong time".
The GNU Backgammon software may be the best example. The GNU software is an open source, which means that anyone can look up the source code of the program, and can verify the purity of the code generator. But it still does not eliminate all doubts, so in the end the only way convincing completely someone with the random of dice is allowing them to make their own analysis and checks and to figure out themselves regarding the dices results.
