In essence, this is just scrabble, and if you want to save your self a whole lotta dosh then buy the original scrabble.
What makes this different to Scrabble is the curved tile racks with a smart phone stand which give players the chance to digitally track their score (can be done in regular scrabble with the supplied score sheets (Scrabble Score Pad) which are available separately should you run out) and to cheat by going online to get spellings for words etc.
Words with friends also has a rotating board which makes game play easier as you dont have to formulate your words with the board 'upside down' as it were. But this can be over come in Scrabble by buying the optional Scrabble Turntable.
In all, nice if you want to spend so much on a game, but you really can not beat the original at nearly half the price.
