There are four prize puzzles on this page: cryptic crossword; quick crossword; wordoku; and coronene. For each puzzle, a winner will be selected from all the correct entries received and awarded a £25 UK book voucher.
You can enter any or all of the prize draws, but each entrant is only eligible to win one of the individual puzzle prizes each month.
