The brief
Normal sudoku rules apply.
Digits separated by a black dot are in a 1:2 ratio (one is double the other.) Not all possible black dots are given.
Adjacent digits along a green line must have a difference of at least 5.
Digits on a purple line must form a non-repeating consecutive sequence (but can be arranged in any order).
Yellow lines are entropic; they must contain one low digit (1, 2 or 3), one medium digit (4, 5 or 6) and one high digit (7, 8 or 9), in any order.
The digit in the red diamond indicates how many lines contain that digit.
