Normal Sudoku rules apply.

Oil and Water: Each cage is either full of 'oil' (even digits), full of 'water' (odd digits), or a mix of both. In all cases, each 'row' within a cage is of just one type (oil or water). Oil floats on water, so even digits will always be in rows above odd digits in mixed cages. Digits may not repeat in cages.

Modular Lines: every three adjacent digits along green lines must be drawn once from each modulo group: {1,4,7}, {2,5,8}, {3,6,9}

Entropy Lines: every three adjacent digits along orange lines must be drawn once from each entropic group {1,2,3}, {4,5,6}, {7,8,9}.

Digits may repeat on Orange and Green lines if allowed by other rules.

Digits separated by a black dot are in a 1:2 ratio. Not all dots are given.
