This month there are only two prize puzzles: the cryptic elements crossword and the quick regular crossword. For each crossword, a winner will be selected from all the correct entries received. Each winner will receive a hamper just in time for Christmas. You can enter both of the prize draws, but each entrant is only eligible to win one puzzle prize.
