Rules
SudokuPad link
- Normal sudoku rules apply.
- Parity Lines: Adjacent digits along a red line must either alternate between even and odd or be completely even or odd. This is up to the solver to determine. Additionally, no 2x2 square can be all odd or all even.
- Digits outside the grid are either X-sums, Sandwich sums, or both. It is up to the solver to determine each clue type.
- X-Sums: Digits outside the grid indicate the sum of the first N digits, where N is the digit in the closest cell to the clue.
- Sandwich Sums: Digits outside the grid indicate the sum of the digits that are placed in-between the 1 and 9 in that row or column.

Nice puzzle :)
Hint to the solvers: it would be much easier to solve the puzzle if not totally forgetting about the 2x2 rule like a dufus like me did :D
