Scrabble was invented by Alfred Butts in 1938. For more than 80 years, Scrabble has been the king of word games.
Today Scrabble can be played online in multiple forms:
Classic Scrabble is available on Facebook and as mobile app. Perhaps the most popular Scrabble-like game today is Words With Friends from Zynga. Wordfeud is another popular Scrabble-like game. Both Words With Friends and Wordfeud are available on iPhone and Android phones. One famous (or infamous) feature of Wordfeud is that players can set the board randomly. So, e.g. double- or triple- letter value boxes can be placed near each other, creating opportunities to generate a much higher score in a single turn as compared to a regular Scrabble board.
