Prime Killers

(Eingestellt am 16. Juni 2025, 09:02 Uhr von Yawnus)

There have been several fascinating mystery killer puzzles where all the cage sums are distinct prime numbers. I started wondering whether it's possible to create a sudoku where any prime could be a cage total.

Soon I discovered that the feat had already been accomplished in Primal Instinct by Agent. However, that version relied on several single-cell cages, so I challenged myself to build one without them. For a long time, it seemed impossible - until I discovered a few key tricks to make it work.

So, here's the result. Enjoy the solve!

Rules:

Normal sudoku rules apply. Digits in a cage cannot repeat and they must sum to a prime number.

Very nice setting. Prime numbers are odd because no 2 is possible for a cage sum.

I made heavy use of the killer cage calculator on that one! But made it through -- very logical and smooth solve once you start thinking about how to break into it properly. Thanks for sharing it with us!
