Название: The master book of mathematical recreations
Автор: Fred Schuh
Many of these puzzles are entirely original; others have been treated in as original a way as possible, including domino puzzles, noughts and crosses, puzzles in mechanics, etc. Puzzle fans will not only enjoy mastering the puzzles, they’ll find their ability to solve mathematical problems increasing. "...exceptionally good value."—Jrnl. of Recreational Math.
