The brief
Normal Sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. The grid is covered in fog, placing a correct digit will clear the cells surrounding that cell. No bifurcation is needed. Digits on a purple renban must form a set of consecutive digits in any order without repeating a digit. Digits in a dotted cage must sum to the sum given in the top left corner of the cage without repeat. Adjacent digits on a green german whisper line must differ by at least 5. Clues outside the grid sum the digits between the 1 and 9 in their respective row/column. Digits separated by a black dot must have one digit double the other (1:2 ratio). Not all dots are given.
