The Daily Printable UK English 78-Word Mystery Fill-In Puzzle is carefully crafted to ensure uniqueness. Throughout the year, every new puzzle will only contain words that have not appeared on this page within the previous week. The puzzle is comprised of words from three to eight letters in length. It is designed to be a bit more challenging than most fill-in puzzles in that the eight-letter words will never cross each others path in the puzzle grid. The same is true for the seven-letter words and also for the six-letter words. As an added challenge, the puzzle will always contain a number of Mystery Words, which are never shown in the puzzle's word list. In the above puzzle, for example, all of the -letter words are Mystery Words. Correctly fit all of the listed words onto the puzzle grid to reveal the Mystery Words. Need help?
