Prime Pincers
(Published on 10. April 2026, 00:00 by NXTMaster)
This is a remake of a very old puzzle. It is now much harder and more satisfying.
The rules are as follows:
The puzzle is available on SudokuPad. Watch out for pincers!
The rules are as follows:
- Place the digits 1-9 once in every row, column, and region.
- Arrows have a value equal to the sum of the digits along the diagonal they point to, like Little Killer.
- Rounded rectangles have a two-digit value equal to the digits they contain in any order (i.e., if the vertical rectangle has the digit 1 above the digit 2, its value is either 12 or 21).
- No two clues have the same value, and these seventeen values must be chosen from the first twenty primes: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71.

Solution code: The nine digits down the main diagonal starting from row 1 col 9 ending in row 9 col 1

Once I actually read the rules and realised you do not have to use all of the primes this went surprisingly smoothly! A well made puzzle.
