Backgammon, the game

I really enjoy the game of Backgammon but don't get to play often because, after all, it is a game for two and my cat hasn't caught on to it yet.  However, I did make a wonderful discovery on my smart phone.  It contains a backgammon game - yeah!!  I find I'm not too bad at the game, which, blissfully, can be set at several different difficulty levels.  I'm honing my skills and someday soon I will challenge my friend Al to a game.  He is the champion of acey ducey backgammon and I would really enjoy beating him once.  Everyone needs a goal...
