Logic Masters Deutschland e.V.

Here is the second puzzle based on an idea I had a few weeks ago, following this one. Again, the idea is not very clear, but the solve is still enjoyable, and some of the logic is worth publishing in my opinion.

I'll post the last one in the coming days.

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.
