Who Sank First?
Rules:
1. Normal sudoku rules apply
2. Dynamic Fog: The grid is covered in fog. Placing correct digits will clear fog in that cell, and may also clear fog in other cells.
3. Anti-Knight: Cells that are a knights move apart (in chess) cannot contain the same digit.
4. German Whispers: Adjacent digits on a green line must differ by at least 5.
5. Renban: Digits on a purple line must form a non-repeating consecutive set in any order.
6. Sequence Lines: Digits on a grey line must form an arithmetic sequence (All adjacent digits must have the same difference). Digits must not repeat, and must be in order starting from one end of the line. e.g. 123 and 963 are valid, 248 and 777 are not valid.
7. Kropki Dots: Digits either side of a white dot are consecutive. If 2 digits are either side of a black dot, one is double the other.
Have fun solving :D
Solution code: Digits in row 1, from left to right
