Entertaining Puzzles, Problems and Tricks

The book "Entertaining Puzzles, Problems and Tricks" by Yakov Perelman is a collection of smart amusements, where behind the effect of "how did he do that?" lies strict logic, keen observation, and precise calculation. There is no mysticism or "mind reading" here - the author shows how amazing tricks, solutions, and paradoxes arise from simple ideas: the properties of numbers, patterns, careful analysis of conditions, and the ability to ask the right questions. Perelman turns problems and puzzles into a real workout for the mind: you learn not to guess, but to prove, to see order in chaos, to find hidden clues, and to gradually uncover the secret. The book is written in a lively language and engages you so much that you want to try it immediately - to show it to friends, argue, test, and come up with your own variations.

"Entertaining Puzzles, Problems and Tricks" is suitable for schoolchildren, math enthusiasts, and anyone who appreciates intellectual games. It's reading that entertains - and at the same time develops: logic, memory, attentiveness, and culture of reasoning.
