Kannappan writes "The complete results of the 2006 Google U.S Puzzle Championship have been announced. The online competition which featured more than 850 participants from all over the world had 23 interesting logical puzzles that were to be solved within the stipulated timeframe of 150 minutes. Usual suspects Zack Butler, Wei Hwa Huang, and Ulrich Voigt emerged in the top bracket but it was Thomas Snyder, a chemistry graduate student at Harvard, who finished with the topmost score of 370 points. Thomas, Wei Hwa, Zack and Roger Barkan will represent United States in the World Puzzle Championship which will be held in October at Borovets, Bulgaria. Interestingly the current world chess champion Veselin Topalov hails from Bulgaria."
