Scrabble word score calculation

When you compute a Scrabble word score, you tally up each letter's point value, which varies from 1 for common tiles like E or T up to 10 for the rare Q and Z. Then you multiply the total by any word premium squares your word covers, like double or triple word scores, and add any letter premium squares for extra points on individual tiles. It's a straightforward but satisfying calculation that can turn a simple word into a high-scoring play.
