Logic Masters Deutschland e.V.

This is the first of three Easter egg bonus puzzles that were originally published in the Yin Yang Journey puzzle pack. The bonus puzzles were ones that could have been part of the main pack thematically, but were created after the main pack was mostly finalized.

Rules:

Normal 6x6 Sudoku rules apply.

Yin Yang: Shade some cells such that all shaded cells are orthogonally connected, all unshaded cells are orthogonally connected, and no 2x2 area is fully shaded or fully unshaded.

Digits in circles may be shaded or unshaded, and count the total number of shaded cells in the 3x3 area centered on that cell (including itself). Note that for circles on the edge of the grid, there will be fewer than 9 cells in that 3x3 area.

Note: Not all possible circles are necessarily given.
