Telegraph Su Doku Bind Up (book)

Plot Summary:

Sudoku is a hybrid: its name derives from Japanese and loosely translated means 'number in an allotted place' and its form can be traced back to the magic squares invented in Switzerland in the 18th century. The result is a numerical brainteaser that is fiendish, compulsive, and, in the simplicity of its rules, 'sublimely beautiful'. This collection, which ranges in difficulty from the gentle through the tough to the diabolical will test your powers of logic... Perfect for those in need of a fix as well as those who have yet to discover the euphoric feeling when you get it right, remember you don't need to be a maths genius to do Sudoku! [1]
