The client has sent this cd-rom to a number of reviewers, and one of them has
reported that the player's data isn't being saved. When they leave the game
and go back to select a player, they don't have any saved players in the
"select player" section.
Kind of taking a stab in the dark here (and operating on far too little

Here is a link to get you started, http://www.gamesgrid.com/backgammon/faq-rng.html a Google search will probably turn up more info as well, although doing the right thing with poor input still produces substandard results in the end -- especially if you or your client is accountable for the quantitative aspects of the game, which includes the statistical qualities of a RNG, process for producing a shuffle/dice roll/etc., and the means for introducing entropy into the process. Back in the early days of F7, I ran a couple industry-standard tests on Math.random() and the results were sufficiently poor to convince me it was not worth running any more tests. Math.random() hides the seeding process from the programmer, meaning that you have no control over entropy. Even if you have a perfect algorithm for producing a dice roll or shuffle, you can not make an argument for the fairness of that game that is in line with standards currently in practice for online casinos. If you don't need to meet such a standard, that's fine, but consider your level of accountability before selecting a method of approach. Gamblers always complain about dice rolls even if you use real dice. How many times have I done that at the craps tables :) This is, of course, why the gaming commission insists on rigid tests for 'fairness' of casino dice.
