Normal sudoku rules apply. There is a secret five digit number. The coloured cells in a row, read left to right as a five digit number, represent a guess at the secret number. If a cell is green, that digit is in the secret number and in the correct position; if a cell is yellow, that digit is in the secret number but in the wrong position; if a cell is grey, that digit is not in the secret number. Cells separated by a black dot must contain digits in a 1:2 ratio. Cells separated by a white dot must contain consecutive digits. Not all dots are given.
