Normal sudoku rules apply.

Path: Draw an orthogonaly conected path that does not branch or touch itself, not even diagonaly. The path starts at R9C9 and ends at R1C1 (marked with squares) and visits each box at least once. Any set of 4 consecutive cells on the path contains digits with different modularity when divided by 4 (one digit from each of these sets: {1,5,9}, {2,6}, {3,7}, {4,8}). Arrow cells are off the path and count the number of path cells in the indicated direction. Circle cells are off the path and count the number of path cells in the cells around it.

Renban: Digits on a purple line form a non-repeating consecutive sequence in any order.

Region Sum Line: Box borders divide the line into segments of equal sums.

Kropki dots: Digits separated by a white dot are consecutive. Not all dots are given.
