Years ago I used to do the word puzzles in magazines like That's Life, etc. My favourite puzzle used to be called a Wordsmith. It provided 9 letters, out of which you made words of 4 or more letters without repeating any and using the centre highlighted letter in every word. There was also a 9-letter word you had to make out of all the letters.
What are these puzzles called now? I really would love to find puzzle books that include them.
