Years ago I was just hooked on Tetris, the faster the game, the better 
Now I'm back my old favorites, chess and backgammon. husband and I sponsored the chess club at our neighborhood school for many years and had enormous fun with the kids.
But my current addiction, without a doubt is Scrabulous. husband also has scrabble on his cell phone. We always have a game going when we have to wait for a table at our neighborhood pub!
