You will be given a string of 4 unique letters. Name all of the words that can be formed using these four letters – remember, each letter must be used at least once, but obviously some will be used more than once for words over 4 letters. For example, ‘arts’ can yield words such as ‘start’, ‘rats’ and ‘starts’. Your string of letters will be one of the 42 strings that have at least 20 possible words that can be formed, based on the current official Scrabble player’s word list. High scores are separate for each unique string of letters.
