The Hidden Paw's First 50 Puzzles

By Akram Najjar

This first puzzle eBook contains a collection of 50 puzzles or riddles with their solutions. These brain teasers require insight to solve but not brute force. Some of them rely on common sense. Others are AHA or GOTCHA puzzles that Martin Gardner loved. There are some that rely on lateral thinking while others require convoluted logic to solve. Of interest are some uncommon puzzles such as cross numbers and puzzles extracted from real life situations.
When selecting the puzzles, two attempts were made:

1) Not to include commonly available puzzles
2) Not to include puzzles that require general knowledge or expertise in specific domains (such as math or algebra).

The intended age bracket is from early teens onwards.
