Online Scrabble trumps actual Scrabble for the following reasons:

1. It calculates your score for you, eliminating the need for basic math skills.

2. You get better letter tiles.

3. It's way, way easier to cheat. Way easier.

4. Built-in dictionary, or, as I call it "The Bullshit Cromulent Detector."

You don't really have to have a good vocabulary to play Scrabble. You'd be surprised how many points you can get out of simple words like "penis" and "vagina".
