Backgammon is a game of skill. Here's why.

"Backgammon has dice so there is a large element of luck"
"I lose because I get unlucky"
"Are the dice rigged."

The less you know about the game, the more you blame luck for losing. The more you truly understand the game, the more you will see how you can overcome the luck factor. This has been proven definitively by the results of the best players. Better players win more, and far better players win far more. Better players are also "luckier" because they position their checkers in a manner that gives them more rolls that are likely to be helpful (lucky) and give their opponent more rolls that will hurt them (unlucky). Backgammon is a game of skill, and the more skill you have, the more likely you are to win. This is proven time and time again in tournaments and match results.
