Games between average Scrabble players are likely to produce a total score somewhere between 400 and 60 points; games between experts (e.g., those who qualify for the National Scrabble Championships held in London each June) often score twice as much. However, if the two Scrabble players co-operate instead of compete with each other, far higher scores can be achieved. For example, in the May 1972 Word Ways, Darryl Francis detailed a Scrabble game in which the combined scores of the two players was 3108 points!
