There are four prize puzzles: crossword (cryptic answers only), wordoku, molecule search and word grid. For each puzzle, a winner and a runner-up will be selected from all the correct entries received. The winners will receive goods from Fortnum&Mason and the runners-up a £25 book voucher. You can enter any or all of the prize draws, but each entrant is only eligible to win one of the individual prizes each month.
