I only recently discovered Sudoku but, like many others, I became quickly addicted to these logical number puzzles, and have been playing an online version at every opportunity. The objective is to fit every digit (from 1 to 9) into every row, every column, and every box in a 9x9 matrix.

Sudoku comes in book format too, handy to take along while traveling, waiting in a doctor's office, or simply to enjoy on a lazy Sunday morning. This paperback volume is first in a series (a boxed set is also available). It opens on an excellent introduction to strategies for Solving Sudoku, including the Ariadne's Thread technique for the most challenging arrays. The puzzles themselves are categorized as Gentle, Moderate, Tough, and Diabolical, and the book includes 132 of them, with answers at the back.

Michael Mepham, who compiled this collection, guarantees 'a good mental workout', telling us that 'As keep fit for the brain, in my experience as a puzzle setter, sudoku is as good as it gets.'
