Modular Line in the Fog

Normal Sudoku Rules Apply

Cells separated by a white dot contain consecutive digits. Cells separated by a black dot are in a 1:2 ratio.

Cells along an arrow sum to the digit in that arrow's circle.

In the fog there is a single modular-3 line. This line is a non-branching line of orthogonally connected cells, which may not orthogonally or diagonally touch itself. It visits all 3x3 regions of the sudoku. On the line, any set of 3 adjacent cells must contain a digit from (147), a digit from (258) and a digit from (369).
