Logic Masters Deutschland e.V.

Rules:

Regular sudoku rules apply; place the digits 1-9 in every row, column, and outlined 3x3 box exactly once each.

Regular slingshot rules apply; for any given arrow, the digit in the cell connected to its tail also appears N cells away in the direction of its tip, where N is the digit in the arrow's cell.

For example, if R1C4 were a 6, R1C5 and R7C4 would contain the same digit.
