Originally published in France, this translation of mathematical conundrums offers English-speaking students, as well as lovers of math games and logic puzzles, an opportunity to meet the challenges devised by the F\'ed\'eration Fran\c c{}aise des Jeux Math\'ematiques for the International Championship of Mathematics. Designed to address a student$\rq$s reasoning skills rather than knowledge, this series of 50-problem sets represents the best of more than decade's worth of championship questions. The three collections are organized by mathematical themes - geometry and symmetry, arithmetic and number theory, logic and algorithmic process - to easily adapt to an instructor$\rq$s curriculum. Each book is arranged with one problem per page for easy overhead use or distribution. The Red Collection is the most ambitious set in the series (grades 9 to college). Puzzles use vectors, transformations, systems of equations, series, and number theory. Problems are solved with compass and straightedge constructions, trigonometry, the Pythagorean theorem, synthetic division, and a great deal of ingenuity.
