RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
GLOBAL ENTROPY: Every 2x2 square of cells must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
MODULO-3 LINES: The grey lines are modulo-3. Any set of three sequential cells along a grey line must contain a complete set of residues modulo-3: one digit from (1,4,7), one from (2,5,8), one from (3,6,9).
KROPKI: Black dots are a 1:2 ratio. Not all dots are given.

Forgetting global constraint makes this much harder, some might say impossible… Not the first or the last time…

Brilliant setting and very absorbing but definitely more challenging than a 2* for me

I have a habit of coloring cells on digit sequence lines such as mod-3 or entropy with red, orange, and pink. When you have a grid as full as this one, it makes the solved grid look like it's filled with sorbet! So I can say, this combination of rules has a nice flavor to it.

Very nice! But more than a 2* for me.
