Sudoku - Number Puzzles

"suuji wa dokushin ni kagiri" Japanese for "the number is alone"

I ran across an article in the IHT on Monday about sudoku number puzzles. They have become the rage in England, with almost every newspaper carrying them, except the Financial Times. These "magic squares" have appeared in illustrations as far back as the 1500's. The strategy is to arrange the numbers from 1 through 9 in a 9 by 9 grid without repeating a number in any row or column.

The Japanese picked up the concept of these puzzles from Dell in the 1970's because numbers work in their language where English alphabet letters do not. Now they have appeared like a virus
