Editor's review

Amusements in Mathematics is a classic puzzle collection by the British recreational mathematician Henry Ernest Dudeney, released free as an e-book by Project Gutenberg. Written in English and belonging to popular mathematics (QA), it covers number games, geometric puzzles, logical reasoning, weighing and division, with problems often set in story-like scenes; the answers give derivations rather than just results. Dudeney's puzzles are known for their ingenuity, low entry barrier, and thought-provoking solutions, making them excellent "gymnastics" for mathematical thinking. Reading them lets you enjoy Victorian puzzle culture while training case analysis, backward reasoning, and spatial imagination. For Chinese readers, the added value lies in encountering mathematical phrasing and everyday vocabulary in the original English, making it light material for bilingual reading or mathematical English. As a public-domain e-book, the layout is mostly plain text and illustrations may be missing in some versions; readers are advised to draw diagrams from the text to aid understanding.

Who it's for

A good fit for

  • Middle-school and adult readers who enjoy number puzzles and logic games and want to sharpen reasoning
  • Math teachers or science communicators seeking fun classroom problems and thinking-training material
  • English learners who want light English material for bilingual reading
  • Readers interested in Victorian puzzle culture and the history of mathematical recreation

Not a good fit for

  • Readers expecting a systematic math textbook with rigorous theorem proofs and exercise systems
  • Beginners who struggle with English and are unwilling to use a dictionary or translation
  • Readers who want instant answers and are unwilling to work through derivations

Reading tips

  1. Start by picking problem types you like chapter by chapter; give each a ten-minute limit, then check the answer and review your reasoning
  2. Prepare paper and drawing tools; for geometry and dissection problems, always draw before reasoning
  3. Treat the English problem statements as reading practice: restate the conditions in your own words, then set up equations or enumerate
  4. Form teams to pose problems and compare solutions, using the same problem to compare the efficiency and generality of different approaches

About the publisher

Project Gutenberg United States · Founded in 1971

Project Gutenberg is a digital publishing project focused on public-domain ebooks. Its publishing direction centers on classic literary works whose copyright has expired, covering genres such as poetry, drama, fiction, and epic. Representative books include Lyrical Ballads by Wordsworth and Coleridge, Proust's Du côté de chez Swann, Shakespeare's Macbeth and The Complete Works of William Shakespeare, Homer's The Iliad, Dante's La Divina Comèdia: Purgatòri, Cervantes's The History of Don Quixote, Volume 2, and Grahame's The Wind in the Willows. Its author resources consist mainly of classic Western writers such as Wordsworth, Proust, Shakespeare, Homer, Dante, Cervantes, Grahame, and Tolstoy. Its publishing feature is the provision of freely accessible ebooks in EPUB and Kindle formats; it is not a traditional publisher, and publicly available information is limited.

FAQ

How difficult are the problems, and what math background is needed?
Mostly elementary mathematics: most problems require only arithmetic, simple algebra, and basic geometry, with a few involving enumeration and case analysis. The difficulty lies not in prior knowledge but in patiently breaking down conditions and trying different paths, so readers from middle school up can start, and math enthusiasts will still find challenging problems.
Does the lack of illustrations in the e-book affect reading?
Some problems involve chessboards, puzzles, or geometric dissection; when illustrations are missing, you need to draw from the text. Keep graph paper handy and redraw the diagrams from the stated conditions—this actually helps you understand the problem. If a problem's description is unclear, skip it or consult another edition with illustrations.
Is the English original suitable for learning English?
It works as light bilingual material. Problem statements are mostly short narrative sentences, with everyday vocabulary and basic math terms that repeat often. Read the statement first to grasp the conditions, guess unfamiliar words before looking them up, then note your solution process in English keywords—training both reading and thinking.

About the author

Dudeney, Henry Ernest, 1857-1930 Author · British · 1857–1930

Henry Ernest Dudeney (1857–1930) was a British mathematician and writer on recreational mathematics, best known for his many ingenious puzzles. Public information about his life is limited, and existing accounts focus mainly on his works. His representative books, Amusements in Mathematics and The Canterbury Puzzles, and Other Curious Problems, show his characteristic approach: he wove arithmetic, geometry, and logic problems into carefully crafted puzzles, explaining how to solve them while keeping the writing entertaining and readable. This style made serious mathematics approachable, inviting ordinary readers to exercise their minds while being amused. Dudeney's puzzle books circulated widely in recreational mathematics and are still regarded as representative works of this kind of writing.
