RULE SET:
Normal Sudoku rules apply. Place the digits 1 through 9 in each row, column, and box.
DIAMONDS (RED): The four cells with red diamonds sum to 21.
(R1C1 + R4C2 + R8C1 + R9C4 = 21)
ENTROPIC LINES (PEACH) Peach colored lines are Entropic lines. Any set of three sequential cells along a peach line must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
MODULO-3 LINES (TEAL): The teal colored lines are modulo-3. Any set of three sequential cells along a teal 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: White dots are consecutive. Not all dots are given.
For our color blind Friends:
Molulo-3 lines (3 total): R6C3-R5C4, R6C6-R8C5, R1C9-R5C5.
Entropic lines (3 total): The remaining lines are the entropic lines.

Incredibly tough visualization, but entirely fair.
