- Normal sudoku rules apply.

- Between lines. The values of the digits along a coloured line must be strictly between the values of the two digits in the attached white circles. Every line has got one and only one colour.

- Circles. Orange circles contain odd digits. Any digit in a circle - either white or orange - indicates exactly how many circles contain that digit.

- Kropki dots. Digits separated by a black dot are in a 1:2 ratio. Digits separated by a white dot are consecutive. Not all possibie dots are given.
