Mallyh. I have done this one without a problem. What I did was answer all the questions - all 4 letter words. As in the example put the first letter of the answer in the box which relates to the question - example is Road so the R goes in the box with No.1 in it. The second letter of the answer goes in the box above (like the 'O' in Example) the third letter of the answer goes in the box to the right (like the 'A' in the Example) and the fourth letter goes in the box on the left (like the 'D' in the Example. So you must put the first letter of the word in the box no that relates to the Question - like Question 2 in the Box 2, Question 3 in the box 3 etc. As you get into it the answers will come together and overlap each other.
Hope that makes sense and helps. I found it quite easy.
