Normal sudoku rules apply.

Teleporting Yin-Yang:

Shade some cells such that all shaded cells are orthogonally connected OR orthogonally connected to a cell with a shaded teleport.

All unshaded cells must be orthogonally connected OR orthogonally connected to a cell with an unshaded teleport.

No 2x2 group of cells may be entirely shaded or unshaded.

Teleports:

The vaguely yin-yang shaped symbols are teleports. Teleports of the same orientation (dark on top vs dark on bottom) always contain the same digit and are the same shading.

Sight Circles:

A digit in a circle indicates how many cells with the SAME shading as it are 'seen', including itself, in all orthogonal directions combined. Opposite shading blocks sight.

Touching Squares:

A digit in a square indicates how many of the up to 8 surrounding cells are of the OPPOSITE shading than the square.
