Standard Dice is NOT random

Its the best app to learn the game on, the layout is the best Ive found, but for the experienced crap players, it soon becomes SO obvious the dice rolls are rigged on the Standard Dice selection which is supposed to be totally random. I can set it up strategically to repeatedly "Seven Out" on command, with particular bets. I even tested it, hoping I was wrong. Unfortunately, I wasnt. I am seriously trying to master a method of play for my trips to the casino. You cant honestly do that with these rigged dice. Boo:-(
