How many people can play Scrabble together?

Although you can play scrabbles with up to four people, the two-player game revolves more on strategies and trying to improve your rack so that you can create plays for yourself as you’re blocking your opponent and predicting their next moves. A two-player game of scrabble looks like a game of complete information when finished, as you can figure out what your opponent is holding after the players have drawn all the tiles – given that you’ve tracked your tiles precisely.
The four-player version of scrabble is more about luck than strategic moves or predicting the next shift in the current. That’s why all major club and tournament games are strictly two-player to keep the challenge hot and the competition hotter.
