Rules:

  • Normal Sudoku rules apply
  • All odd numbers in the grid have to form a single orthogonally connected region
  • Adjacent pairs of numbers on a line must sum to a prime number
  • Not all possible lines are given

The following table may help you solve it: it shows for each pair of odd numbers what even numbers sum to a prime with both numbers, and similarly for pairs of odd numbers.

Lösungscode: Please enter the digits from the bottom row as a single number (e.g. 123456789).

The key logic in the first puzzle was very neat, but worth little if reused. It's therefore only right - and impressive - that this puzzle uses the same rules but different logic.

And the aesthetics is just great (something Simon A. also remarked on with the first puzzle).
