The brief
Normal Sudoku rules apply. Digits seperated by a black dot must be in a 1:2 ratio. Cells on a grey square are even. Digits along a thermometer must increase from the bulb end. Cells in a cage must sum to the clue in the top left corner, with no repeats. Cells along an arrow must sum to the digit in the circle. Cells on a grey circle are even.
