Usual sudoku rules apply. Also, the numbers in the shared set of 3 by 3 box is filled in identically, for both of the individual sudokus.

To begin, look at the digit which occurs most frequently in the grid. In which rows, columns and boxes is it missing? Also look at rows, columns and boxes which are almost complete – which numbers are missing and where could they go? The rest is up to you!

Complete the grid so that every row, column and 3x3 box contains the letters AEFGINRST in some order. One row or column contains a 7-letter word - what is it?

Each face is a separate Sudoku puzzle. The three adjacent 9x9 corner squares count as one 9x9 square shared in common.

Insert the numbers one to seven in each row and each column, taking care that no number is repeated in a particular row. The only symbols to guide you are the signs for “greater than” and “less than”.

Fill in the blank squares of the grid, using 1 to 9, without repeating any number in any run line. The lines must be filled in with numbers whichadd up to the total in the shaded box at the top or beginning of each line. A number in the bottom half of the shaded box gives a downwardstotal; in the top half, it’s a horizontal total.

In Japanese, hitori roughly translates to ‘leave me alone’, and you’ll understand why when you pick up the rules to this puzzle.

To complete the puzzle, every row and column must not contain the same digit twice. You’ll notice in the example given here that there are repeated numbers, so it’s your job to shade out just enough numbers to satisfy the master rule.
