The brief
Normal 6x6 sudoku rules apply: each column, row, and 2x3 box must contaiin all the digits from 1 to 6. Cells that appear in the same position within a box cannot contain the same digits. Digits on a grey line read the same forwards as backwards. Digits within a circle must appear at least once in the four cells touching the circle. Digits in a cage sum to the total given in the top left corner of the cage. Digits cannot repeat within a cage. Digits on a grey square are even. Digits seperated by a black dot are a 1:2 ratio. Not all dots are given.
