Logic Masters Deutschland e.V.

Normal Sudoku rules apply.

Draw a one-cell-wide loop of orthogonally connected cells. The loop may not touch itself, not even diagonally.

Digits along each arrow sum to the digit in its circle. Each circle is on the loop.

In one direction along the loop, digits strictly increase from each circle up to the cell immediately before the next circle. The direction must be determined by the solver.
