Who is medium Killer Sudoku for?

Killer Sudoku is a classic number logic puzzle in the family of Sudoku. It’s quite similar to classic Sudoku in many ways, but has its own nuances which make it a lot of fun to play.

Overall, Killer Sudoku is a great puzzle game for beginners. If you’ve never played Sudoku or other number games, you might want to start on easy levels first. On the other hand, if you feel comfortable with the rules or have played sudoku before, try medium Killer Sudoku levels. They offer enough numbers from the start not to make you think too hard, but still pose a great amount of challenge to be entertained.

Medium Killer Sudoku strategies

While it may be absolutely fine to play beginner Killer Sudoku levels intuitively by just trusting your gut, medium Killer Sudoku requires the grasp of a few basic strategies. They’re quite simple, let’s review one of them down below.

“Innie/Outie” strategy
When you’re completing a specific row or a block, you might notice it’s made up of a few full cages and a cell that is a part of another cage. We would call that cell “an innie” and you can see an example of it in the image below.

We know that the sum of all numbers in a block, row or column is always 45. Hence, 45 - 14 - 16 - 13 = 2. That would be the value for the last call. As the total value of that cage is 5 we can easily figure out “the outie” – 5 - 2 = 3. This is a very simple yet effective strategy for medium Killer Sudoku levels.

Why you should play Killer Sudoku

As you see, Killer Sudoku is quite simple, yet thought-provoking and challenging puzzle game. It’s a great way to distract yourself from the routine tasks or give your brain a workout when bored.
