536 Puzzles and Curious Problems
Throughout the span of twenty years, independent mathematician Henry E. Dudney composed a riddle page named "Perplexity" for The Strand Magazine. Dodney was hailed by Martin Gardner, a veteran manager of Logical American's Numerical Segment, as "Britain's most noteworthy riddle producer", uncommon in both amount and quality for his developments. This arrangement of Dudeney's long-out of reach moves vouches for the riddle producer's ability for making brilliant and convincing riddles.
This interesting riddle depository starts with a determination of number-crunching and mathematical issues, including difficulties including cash, time, speed and distance.
Geometric puzzles come next, as do topological and combinatorial puzzles with magic squares and stars, path and grid puzzles, and map coloring puzzles. A collection of games, dominoes, matching, and unranked puzzles complete the collection. There are solutions to all 536 problems in the book, and charming illustrations bring the book to life.
