Jools..I used to avoid them at all costs, and then started looking at the answers to them the next day, to see what the answer was. Sometimes I saw it, sometimes not. When you start them though, you soon become 'addicted'. It really gives the brain a workout! You seem to get into a compilers way of thinking, but then certain ones, like the ST today...I know I will really struggle with, just can't get most of them.
There is always help readily available and given gladly on here, they are wonderful and clever! It's worth having a go.
Enjoy your puzzles today..good luck Pauline x
