The metapuzzle Single, Solitary S has been out for a week now. Check the hint below for your chance to solve it.
Once you finish with that, check out the first puzzle of a new set, Questions. You will need your other eight answers to crack this one.
This is a sudoku puzzle. Start by placing the answers of length three, five, and six into their respective green regions. There is then only one way to place the four-letter answers into the grid which follows the rules of sudoku. Once you have solved the puzzle, you will find your nine-letter answer hidden in the grid.
