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 unshaded.

Sight Lines: Digits in caged cells indicate how many cells of the same color (shaded or unshaded) are seen orthogonally from that position, including itself. The "other" color blocks vision.

HDR Thermos: Values on thermometers must increase from the bulb end. For the purpose of evaluating thermometers, digits in shaded cells have NEGATIVE values while digits in unshaded cells have POSITIVE values.
