Logic Masters Deutschland e.V.

Rules:
Fill the grid with digits from 1 to 9 so that each row, column, and 3×3 box contains each digit exactly once.

Pulsar Cells:
Some cells contain a diagonal marker indicating one of the two diagonal directions (NW–SE or NE–SW). For each such cell, consider the two cells located exactly two steps away along that diagonal. The value in the marked cell equals the value in the cell two steps downward (toward increasing row index), raised to the power of the value in the cell two steps upward (toward decreasing row index).

Pointer Cells:
Some cells contain arrows pointing to one or more adjacent cells. The value in each such cell equals the arithmetic mean of the values in all cells it points to.
