SUDOKU

What is Sudoku?

Sudoku is a logic puzzle that has been driving the world insane. It's based around a nine by nine grid (although there are variations), in which some numbers have been entered; all you have to do is fill in the rest of the grid. Easy, eh?

Every Sudoku puzzle follows one and only one rule, which is this: In a Sudoku Puzzle, every row, every column and every region contains the numbers One to Nine, once.

A short history of Sudoku

The origins of Sudoku are shrouded in mystery. Some claim that it is an ancient Japanese puzzle based on the forbidden teachings of an infamous group of martial artists, who would dazzle opponents with their logical finesse before chopping their legs off. Others trace it back to an eighteenth-century Swiss mathematician who invented it as a distraction from all those hilarious bloody cuckoo clocks. Perhaps the most plausible theory is that it emerged out of Area 51 as a deadly newspaper-borne virus designed to destroy all productivity and rational thought on earth. But who knows for sure? Well, if you listen to all the hype in the papers and the death-threat internet debates, apparently no-one does. What we do know is that a bloke named Wayne Gould spotted it in a Japanese bookstore, started creating his own and then sold them on to UK newspapers, and then everything went, well, kind of insane really.

Let's face it, no-one cares where they came from. They're here, you need them like finest crack cocaine, and here at Indigo Puzzles we're ready and willing to provide. What can we say? We just Love to Give.
