Grouping All but Two

Rules:

• Normal sudoku rules apply.


• Divide all cells in the grid except for r9c7 and r9c9 (the two grey cells) into groups of orthogonally connected cells. Every group contains exactly one cell with a white circle. The digit in a circle cell, N, indicates the number of cells in that group. All cells in a group have the same parity as N. r9c7 and r9c9 are not in any of the groups and may be any digit, but are still affected by normal Sudoku rules.


• As an example, a circle cell containing a 4 is in a group of 4 orthogonally connected cells that are all even.


• *Note: Adjacent cells with the same parity could still be part of different groups; the parity restriction solely affects cells within the same group.*


• Digits separated by a white dot are consecutive. Not all dots are given.
