SUDOKU

There are two types of people in the world today: those hooked on Sudoku, and those yet to be converted.

Sudoku is a mind-bending and pleasantly addictive number-placement game that exercises your brain and helps you escape from the everyday stresses of life.

Puzzles are ordered according to their difficulty, and organised into four categories: Painless, Tricky, Nasty, Migraine.

Each puzzle is a nine-by-nine grid divided into nine horizontal rows, nine vertical columns and nine three-by-three blocks. Each puzzle is presented with just a few numbers showing. To complete each puzzle, the player must place numbers from 1 to 9 in the empty cells so that, when the grid is full, every column, row and block contains all the numbers from 1 to 9 with no repeats.

Sounds simple - but then all the best puzzles do, until you start playing. Good luck, enjoy, and be warned: if you're not hooked already, you soon will be!
