Rules 1:

6x6 Chaos Construction rules apply: Divide the grid into 6 orthogonally connected regions with 6 cells each.

Place the digits 1-6 exactly once into every row, column, and region. It is up to the solver to determine where these regions are.

No two circles may be in the same region. A digit in a circle indicates how many of the (up to 9) surrounding cells are in the same region, including itself.

A digit in a square indicates how many of the surrounding cells are in a different region.
