The brief
Normal sudoku rules apply.
Along thermometers, digits must increase from the bulb end.
Digits along a purple (renban) line are a set of consecutive, non-repeating digits in any order. All crosses act as 5-cell renbans.
Digits separated by a white dot must be consecutive. Digits separated by a black dot must be in a 1:2 ratio.
The grey circle contains an odd digit.
Cells in the same position within two 3x3 boxes cannot contain the same digit (disjoint sets).
