The brief
Normal sudoku rules apply. Place the digits 1-9 once each in every row, column and 3x3 box. Digits in a dotted cage without repeat, sum to the total given in the top left corner of the cage. Cells separated by a black dot has one digit double the other (1:2 ratio). Adjacent digits on a green line must differ by at least 5.
