Backgammon is part luck as far as the dice go. However what you do with the dice rolls is the skill part. The players with better records and ratings are the ones who know how to use the dice rolls to their best advantage. IS there luck involved? Of course.

Nonetheless, if your primary objective is to have fun then what does any of the ranking stuff matter.
