To quickly calculate any Scrabble word's score, assign each letter its tile point value: 1 for common letters like A, E, I, and 10 for Q and Z. Add the points for all letters in the word, then multiply by any premium squares under your tiles, adding any word multipliers if the whole word covers a double or triple word score. Don't forget to add 50 extra points if you use all seven tiles in one turn.
