Otherwise, Scrabble is a great game but not for everyone. One should bring patience, as it can take up before you or another player has found a word and stopped his train. I also recommend using a Scrabble dictionary (there are also online) to play, because they avoid any dispute from the outset.
For children I think the game is not so good because you can write for many difficult words and all grammatical forms, to which one does not just come at a young age and of course one drawback would in the game.
