This book includes two hundred mathematical puzzles or numerical games, aimed at entertaining those who engage with them.

It is intended for people of all ages, as an effort has been made to ensure that the mathematical knowledge required to solve the puzzles is minimal. The level of difficulty is quite broad. Thus, even young elementary school students will find plenty of numerical games to engage with.

For middle and high school students, there are many puzzles related to the subjects taught in school.

The book is divided into three parts: the first part includes the puzzles organized into various themes, the second part contains the solutions to the puzzles, and the third part provides only the results of the puzzles, allowing the reader to refer there to check each time if they found the correct answer.
