Chaos Construction:

  • Divide the grid into orthogonally connected regions, and place the digits 1-6 once each into every row, column, and region.
Yin Yang:
  • Shade some cells so that all cells of the same shading are orthogonally contiguous, and no 2x2 area is entirely the same shading.
Shaded Copycats:
  • The value of a shaded cell is the digit in the cell rotationally opposite itself (180° rotation about the center of the grid).
  • The value of an unshaded cell is its digit.
Cave:
  • The value in a circle is equal to the number of cells in the same region that it "sees" in all four cardinal directions combined, including itself, where region borders and the edge of the grid blocks vision.
  • ALL CIRCLES ARE GIVEN.

Keeping track of shading and regions was perhaps the most difficult part. I had to switch back and forth on which I used the colours for.

Keeping track of region building versus yin yang shading was a bit of a mental workout, but the way the symmetry of the clues works with copycat logic was really cool. Thanks!

Really well put-together. Interesting pattern at the end and good use of the negative constraint
