Hitori

Hitori

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.
