Stanbesida-there is a section at the back of Puzzle Monthly called Puzzle Pointers, where subscribers can write in and tell us how they (or their wives) have some tips on how to tackle various types of quizzes. For Shaneystar & my benefit, please will you write a small article about Switchback, and Snakes & Letters, because I,ve never been able to understand them either.The instructions given to tackle them never change, especially switchback , and I'm never sure if all the squares should have letters in, as mine never fit!
