su doku
n.— «“You won’t find Su Doku in a Japanese dictionary,” said puzzle creator Wayne Gould in The Times of London. “It’s a coined word, made up by a Japanese publisher.…As I understand it ‘Su’ stands for number, and ‘Doku’ has some notion of singularity or bachelorhood about it, emphasizing perhaps that there is only one of each number in each unit (row/column/box).”» —“Su Doku Q&A” News-Sentinel (Fort Wane, Ind.) Apr. 4, 2005. (source: Double-Tongued Dictionary)
