Normal sudoku rules apply. In cages, digits must sum to the small clue in the top left corner of the cage. Digits may not repeat within a cage. Along thermometers, digits must increase from the bulb end. Digits on a black dot must have a ratio of 1:2, digits on a white dot must be consecutive. Not all possible dots are given. Cells with a grey circle have to be odd, cells with a grey square have to be even.
