Can only visit the street once, but the corners any number of times. Are there any "rules" for spotting the correct answer, or is the only method a process of elimination, drawing the routes around the streets. Thanks.

Thanks Chad, it's reassuring to know that I am not alone. Sometimes I, or ds, can put the pencil on the paper and draw the correct path straight away. Other times, we can end up drawing forever b****y circles, squares, triangles etc, and not get anywhere.
