Amazon.com description: Product Description: “Word Judge for Clubs and Tournaments (Wj2) is a compilation of two- through twenty-letter words playable in North America. The Super Scrabble® players in Tustin necessitated this compilation. Although there are many words in the World English international word list that are not acceptable in North America, it is good to know that the two- through twenty-letter words included in Wj2 are valid and playable in the international tournaments such as the World Scrabble® Championship, Scrabble® Champions Tournament sponsored by the MindSports International, and the global Super-S Club games, whose players absolutely depend on Wj2 for adjudicating words with more than sixteen letters. Try playing the longest word you know, albeit in multiple steps. The joy of playing words beyond the fifteen-letter-word range is inexplicable. It is a rare occurrence that truly happened in Albany, W. Australia. Yes, it's doable. What's your favorite word game?”
