Logic Masters Deutschland e.V.

- Normal sudoku rules apply.

- Reflected parity: Every cell in the grid is paired with the cell reflected across R5C5 (for example R1C3 is paired with R9C7; R4C2 is paired with R6C8 etc. – see example below). Pairs of reflected cells have the same even/odd parity.

- Dynamic fog: The grid is partially covered with fog. Correctly placed digits will clear the fog of a cell’s reflected cell. Guessing is not required.

- Straight Arrows: Digits along an arrow sum to the digit in the connected circled cell. Digits may repeat on an arrow if allowed by other rules. All arrows in this puzzle are straight.

- Killer cages: Digits in cages must sum to the number in the top-left corner and cannot repeat. All cage sums are given.

- Kropki dots: Cells connected by a white dot contain consecutive digits. Not all possible dots are given.

- XV sums: Digits separated by V sum to 5; digits separated by X sum to 10. Not all possible XV sums are given.

Below is an example of reflected pairs of cells. Cells of the same colour represented reflected pairs of cells.
