Sudoku
What's it all about bloggers has anyone tried to complete one of these puzzles, if so how long did it take. As my brain does not work too good I ahve never attempted one. It seems to be a craze that has popped up all of a sudden is it just to fill Carol Vordeman's pockets again with mathematical trivia or an old "chinese" game. Fill me in bloggers with the history of this game.

Never heard of it Jim. I'm as mystified as you are. I've just 'googled' Sudoku and it looks like a number puzzle.
In Japan, they don't do many crosswords. They do Su Doku instead. Yet, although the name is Japanese, roughly translating as as "Number Place" the puzzle itself, originally, may not be.
Unlike a crossword you don't need to speak a particular language to doa Su Doku puzzle. Technically, you don't even need to know how to count. You sinmply have to fit a digit from 1 - 9, in any order, into each row ( left to right), each column ( top to bottom) and each box ( of nine squares).
A good tip is to think initially in boxes, or better still, bands of boxes. Look for pairs of numbers, from which you can infer a third. If the top left box has a 7 in it, say, and the bottom left box also does, then it shouldn't be too hard to figure oput where to put the 7 in the middle left box.. TYry working this way horizontally too. If there seems to be two possibilities, just make a note, and move on.
Every puzzle can be solved from the clues provided, by logical steps from beginning to end. Done properly, a puzzle shouldn't require you to guess. Do remember -- there is only one solution to each puzzle. If yours doesn't match the solution provided, look again because, somewhere, you've gone wrong.
