Not all problems in this field require a knowledge of advanced mathematics, and thus recreational mathematics often piques the curiosity of non-mathematicians and inspires their further study of mathematics.

This genre of mathematics includes logic puzzles and other puzzles that require deductive reasoning, the aesthetics of mathematics, and peculiar or amusing stories and coincidences about mathematics and mathematicians. A logic puzzle is a Puzzle deriving from the Mathematics field of Deduction. Deductive reasoning is Reasoning which uses deductive Arguments to move from given statements ( Premises to Conclusions which must be true if the Aesthetics or esthetics ( also spelled æsthetics) is commonly known as the study of sensory or sensori-emotional values sometimes called Some of the more well-known topics in recreational mathematics are magic squares and fractals. In Recreational mathematics, a magic square of order n is an arrangement of n ² numbers usually distinct Integers in a square, such A fractal is generally "a rough or fragmented geometric shape that can be split into parts each of which is (at least approximately a reduced-size copy of the whole"

Logic puzzles are a common type of mathematical puzzle. A logic puzzle is a Puzzle deriving from the Mathematics field of Deduction. Conway's Game of Life and fractals are also considered mathematical puzzles even though the solver only interacts with them by providing a set of initial conditions. "Conway game" can refer to games as defined by Surreal numbers which Conway also developed A fractal is generally "a rough or fragmented geometric shape that can be split into parts each of which is (at least approximately a reduced-size copy of the whole"

Mathematical Games was the title of a long-running column on the subject by Martin Gardner in Scientific American. Martin Gardner (b October 21, 1914, Tulsa Oklahoma) is a popular American mathematics and science writer specializing in Recreational mathematics Scientific American is a Popular science magazine, published (first weekly and later monthly since August 28, 1845, making it He inspired several new generations of mathematicians and scientists through his interest in mathematical recreations. Mathematical Games was succeeded by Metamagical Themas, a similarly distinguished but shorter-running column by Douglas Hofstadter, and afterwards by Mathematical Recreations, a column by Ian Stewart. Metamagical Themas is an eclectic collection of articles written for Scientific American during the early 1980s by Douglas Hofstadter, and published Douglas Richard Hofstadter (born February 15 1945 in New York New York) is an American academic whose research focuses on consciousness thinking and creativity Ian Nicholas Stewart (born 1945) is a professor of Mathematics at University of Warwick, England and a widely known popular-science and science-fiction
