The brief
- Normal Sudoku rules apply.
- Cells separated by a knight's move in chess cannot contain the same digit.
- Digits along a megenta Renban line form a set of consecutive non-repeating digits in any order.
- Digits in a cage do not repeat and sum to the clue in the top left.
- A black dot between cells indicates cell values with a 2:1 ratio. Not all dots are given.
- The digits along each arrow must sum to the digit in the circled cell.
- Adjacent cells connected with an X must sum to 10.
- Cells with a filled circle must be odd.
