Games?

I am not a gamer - at all. I wouldn't know how to play a video game if you held a gun to my head. My gaming experiences involve board games such as Sorry, Monopoly, Taboo, Battleship, and my all time favorite - Scrabble. I need some suggestions for online games to get me acquainted with the gaming world. Something simple to start with would be great. Can anyone point me in that direction??
