The brief
Normal sudoku rules nearly apply: Place the digits 0-8 in each row, column and 3x3 box. Prime Lines - Digits along a pink line must sum to the product of the prime numbers along that line. Digits may repeat along a line if allowed by other rules. (A product can consist of 1 number) Anti-knight- Cells separated by a knights move cannot contain the same digits. Kropki dots - Cells separated by a black dot must be in a 1:2 ratio. Cells separated by a white dot must be consecutive (not all dots are given). No two lines may have the same sum.
