  • Yin Yang: Shade some cells so that all shaded cells are orthogonally connected, and all unshaded cells are orthogonally connected. No 2x2 area is fully shaded or fully unshaded. The value of a shaded cell is one greater than its digit, the value of an unshaded cell is one less than its digit.
  • Region Sum lines: Box borders split blue lines into segments, the sum of the values on a segment is the same for each segment. Different lines may have different totals.

This puzzle felt so creative in the way it was set up and facilitated steps I didn't see coming without ever being obtuse. Brilliantly set.

Fantastic puzzle with some great deductions. Recommend persisting with it even if the ruleset is bending brain and it's a struggle to find the breakin, as it's very much worth it.
