Frame Sudoku

By djape | Published: March 4, 2014
A novelty for this site – Sum Frame Sudoku! 🙂 No, it’s not an Outside Sudoku. It’s more of a Killer Sudoku Variant: the numbers outside the grid tell you the sum of the 3 numbers closest to it. So, yes, in a way it is also similar to Outside Sudoku, but here you do have to process the sums of 3 numbers (always 3!), hence it is more a killer variant. The rest of the rules are standard Sudoku rules. I guess that’s clear enough for the rules of Frame Sudoku. If not, please ask questions. UPDATE: I decided to present you not one, but two frame sudoku puzzles! First one is EASY, the second one is BRAIN. 🙂 So enjoy!

    Your sum-frame puzzle looks intriguing, but why start us out with a BRAIN?

    I need to start with an easy/cool one!

      Donna, have you tried this one? I don’t think it’s too difficult… if you do, I will post an easier one. 🙂
