Rules: All normal variant rules
- Normal Sudoku rules apply. Place the digits 1 through 9 in each empty cell. Digits must not repeat within the same row, column, or box.
- Digits cannot repeat along diagonals marked in blue.
- A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are shown.
- The digits along each arrow must sum to the digit in the circled cell. Digits may repeat along an arrow if permitted by other rules.
- Cells with a filled circle must be odd. Cells with a filled square must be even.
- The digits in a cage must sum to the number printed in its corner. Digits may not repeat within a cage.
Solution code: Column 3 and 7, from top to bottom.
