Normal sudoku rules apply. Each line in this puzzle is either a Renban Line or a Nabner Line. The solver must determine which is which. Digits along a Renban line must form a set of non-repeating consecutive digits in any order. No two digits along a Nabner line can be consecutive, regardless of their position on the line. Digits in cells separated by a black dot are in a 2:1 ratio. Digits in cells separated by a white dot are consecutive. Cells marked with a grey square contain even digits. Cells marked with a grey circle contain odd digits.
