Oh dear - I am still struggling despite many helpful posts.
Let me test my understanding. You start with J ( or do you start with one of the letters surrounding it?). You then move 10 places (if it is J) to another letter and so on?
If someone could give me the first three letters of the first circuit I'll battle on. If not, I'll go and have a cry at the other end of the pond and await next week's puzzles.
Bear with me first division players. It keeps me out of mischief and Mrs Seal is pleased.
Thanks again
