In SCRABBLE® crossword game (hereafter referred to simply as SCRABBLE), playing all seven tiles at once entitles one to a 50-point bonus, which, when added to the score for the word(s) formed, often results in a single turn of 70 points or more. Even 100-point turns can occur when the tiles are played on one or more premium squares which double or triple the values of letters or words. Theoretically, in fact, well over 1,000 points are possible when seven tiles are added in key positions to eight tiles already on the board to produce several words including a 15-letter word spanning two double-letter squares and three triple-letter squares.
