Link to the first puzzle
I recommend you check that one out before trying this one. It has an example to better illustrate the ruleset.
The rules to this puzzle may look scary and long but they’re not complicated at all once you understand them.
Rules:
- Normal Standard Sudoku rules ALMOST apply.
- Each 3x3 box, column and row must be filled with numbers from 0 to 9.
- 0 will take the place of a digit if that digit is surrounded only by prime numbers. Surrounded means all orthogonally adjacent cells have to be composed of only prime numbers. All instances where a digit is surrounded by prime numbers, that digit is replaced by 0.
- There are 9 different digits that are replaced by 0. (That means 0 takes the place of 1 to 9 all while respecting the standard rules, so no 0s in the same box, row or column).
- The digit that is replaced by 0 cannot appear in the same box, row or column as the 0 that took its place.
- Outlined regions are cages. The sum of digits in a cage is given in the top-left and digits cannot repeat. The digits that are replaced by 0s are counted as 0 in the sum of the killer cage.

Solution code: Row 1 followed by column 4 (no spaces and no commas) ie (123456789987654321) (The solution code will obviously have 0s in it)

I really liked the idea behind the 0, but I didn't notice at first that 1 was not a prime number, so it took me a while to break in!! Thank you again for another brilliant work of art!

What an emotional rollercoaster! I'm very surprised that the 0's actually make the path so smooth it's just so intriguing to go deeper :)
