This reviewer applauds the republication of his genius in 'The New Martin Gardner Mathematical Library' series, complete with revised explanations, new insights, up-to-date reference links, and brief surveys of recent discoveries … it is worth getting the new editions and sharing these new gems!' J. Johnson, Choice
'I recommend you approach this book on a Sunday afternoon, with paper and pen, a few biscuits for brain-power and a good hour to spare for puzzling. It is worth it.' Charlotte Mulcare, + plus Magazine
