Get Ready for Sudoku

Apparently something called Sudoku is quickly taking over all land masses east of the Atlantic and is quickly headed for the U.S. Billed as "more addictive than tetris" it is a numerical cousin to the crossword puzzle. The Japenese grid game has England in fits and the New York Times is supposedly mulling a weekly puzzle right next to its holy-grail-of-newspaper-puzzle-games Sunday crossword. Refined readers may appreciate the Economist's snapshot, but the best reading on this subject is Seth Stevenson's synopsis of Sudoku mania at Slate.
