Summersdale Publishers, 2007. — 160 p. — ISBN: 9781840245578.Good Old-fashioned Challenging Puzzles is a selection of mathematical brain-teasers from Dudeney's book Amusements in Mathematics, first published in 1917 and hailed by The Spectator as ‘not only an amusement but a revelation'. Some of the problems are, as Dudeney admitted, ‘not unworthy of the attention of the advanced mathematician’.
