Scrabble scoring system
https://extra-wiki.win/index.php/Scrabble_scoring_system
In Scrabble, each letter tile has a point value from 1 for common letters like E and A up to 10 for rare ones like Q and Z. You add up the values of all letters in a word, then apply premium square bonuses like double or triple letter and word scores, which can really boost your total.
