Soduku

So has anyone over on the other side of the Atlantic heard of “Soduku” this Japanese puzzle game which involves creating rows and columns of numbers ranging from 1-9 in a 9×9 grid? It’s everywhere in London–every book store has cheap pulp booklets full of the puzzles–and I’ve started to get somewhat enthralled with the premise of the game, although I have dutifully avoided addiction. But knowing me that might be around the corner.
