Have you calculated the odds? You know, some weird stuff can happen over the board too. I also had disgusting losses but I also had disgusting wins, that's what's beautiful in backgammon. It's a game of both skill AND luck. You were just unlucky, try to play anywhere else, I won't name the websites but there are some that people play specifically backgammon on. Three rolls of 6-6 in a row isn't that big of a deal when you calculate the odds. Computers CAN randomly generate numbers, it so happens your roll was a bad one. Do you do the same when you play over the board? No, you probably call your opponent a lucky bastard, so why not in this context too?
