SPIRAL

The completed puzzle is made up of two long chains of words – one reading inwards from box 1 to 100; the other outwards from 100 to 1. Only one letter is allowed in each box. Once you’ve completed the puzzle, the letters in the blue boxes can be rearranged to spell out the prize word, which this week means ‘tune’.
