1) The Nature of the Puzzles and Card Tricks
These brain teasers require insight to solve but not brute force. Some rely on common sense. Others are AHA or GOTCHA puzzles that Gardner loved. There are puzzles that rely on lateral thinking while some require intense logic. I attempted to move away from commonly available puzzles while including uncommon puzzles such as cross numbers and puzzles extracted from real life situations.
I have been solving and collecting puzzles since i was 15. My first introduction to "puzzledom" was when a teacher introduced me to Martin Gardner's Mathematical Games column in Scientific American. Gardner had the regular practice of devoting a single issue to 9 wonderful puzzles. Gardner's books now adorn my bookshelf.
