Rules: Normal Sudoku Rules apply.

Normal 6x6 Sudoku Rules Apply.
Along each blue line, the sum of all digits along that line must be equal to the product of the primes along that line. (e.g if a line had 1,2,3 along it the line would need to add to 6 as 2x3 =6. Alternatively if a line had 1,2,4 this would not be allowed as 2 (product of primes) is not equal to 7 (1+2+4))
Numbers cannot repeat on a line. Different lines may have different totals.
Anti-Knight - Digits separated by a knights move (in chess) cannot be the same.
Kropki dots (ratio) - Digits separated by a black dot must be in a 1:2 ratio.
