Logic Masters Deutschland e.V.

Normal sudoku rules apply.

Digits separated by a black dot are in a 1:2 ratio. Not all dots are necessarily given.

Digits must not repeat on the marked diagonal.

Each grey cell is either maximum (higher than its four orthogonal neighbours) or minimum (lower than its four orthogonal neighbours).
Pairs of grey cells that are symmetrically placed across the marked diagonal (eg r1c3 and r3c1) are either both maximum or both minimum.
