Logic Masters Deutschland e.V.

Rules:

-Normal sudoku rules apply.

-Cells with outward-facing arrows must contain higher digits than their orthogonal neighbours.

-Cells with inward-facing arrows must contain lower digits than their orthogonal neighbours.

-Digits along an arrow sum to the number in the connected circle.

-Grey lines function as arrows so digits along them sum to either the connected circle or the connected pill (oval) which is a 2-digit number reading left-to-right.

-When a grey line passes through the edge of the grid, it re-enters the grid at the opposite side, continuing as if it were 1 connected line. E.g. the line beginning at R9C4 goes to R9C3 then connects to R1C3 and R2C3.
