The second entry in this series is a bit of an oddity. Most of these will be combinations of Nuri-Maze and basic pencil puzzle genres, while this one is on a Latin Square and has more complex rules. Make sure to read the rules carefully, and watch out for the negative constraints. Enjoy!

Rules:

Latin Square: Fill the grid with digits 1-9, such that no digit repeats in any row or column.

Nuri-Maze: Shade some cells to form a maze. Circles cannot be shaded. There can not be a 2x2 square of all shaded or all unshaded cells. For each pair of unshaded cells, there is exactly one path of edge-adjacent unshaded cells connecting them, i.e. all unshaded cells form an orthogonally contiguous area without any loops.

Interaction: All shaded cells contain even digits and all unshaded cells contain odd digits. White circles must be part of the path from S to G, and digits inside white circles are greater than all their edge-adjacent neighbours. Grey circles must not be part of the path from S to G, and digits inside grey circles are smaller than all their edge-adjacent neighbours. All valid white and grey circles are given.

Oddsweepers: Digits in squares count the number of odd digits in the (at most) 3x3 square surrounding the clued cell, including itself. All valid squares are given.
