フィラデルフィアで開催された 2009 年全国数独選手権で、米国と数独の世界チャンピオンである Thomas Snyder は $10,000 の優勝賞金を目指しますが、最後の数秒で速すぎてミスを犯します。 3 分後、Tammy McLeod は正しいグリッドでトーナメントに勝利し、US Sudoku チームに参加しました。 また、3 位に入賞した Eugene Varshavsky は、フード付きのスウェット シャツを着てグリッドの前で動かず、トーナメントの早い段階で不正行為を行った疑いがありました。 数独と競技パズルの詳細については、motris.livejournal.com をご覧ください。

  1. the title and description are way cheeky…. Snyder is a several time sudoku champion and an ambitious guy — no reason to be weird and point fingers at him like this.

  2. i copied it, but after a few minutes, i realised i couldnt continue. thenn i realised, i copied one of the numbers incorrectly. it took me about 10 minutes.

    i found this relatively easy. if you want a real challenge, try evil puzzle 7,340,208,238 at (websudoku). let me know how you go, and remember, no inserting guesses, only use logic.

  3. i ran the championship puzzle through a solver and it said the difficulty was "mild"

    huh. they sure made it easy.

  4. on 5th row + 8th column put 4 in place of 6
    and on 9th row rplace 6 and 4 with each other.
    then it will be correct.

  5. It took me 25 min on computer software to do this puzzle. It was also a pretty puzzle, a rather good puzzle for a championship. Thanks for sharing
