XV : Barricade

The dwarves explored the caverns once more, and found, as they expected, that only the Front Gate remained open; all the other gates (except, of course, the small secret door) had long ago been broken and blocked by Smaug, and no sign of them remained. So now they began to labour hard in fortifying the main entrance, and in making a new path that led from it. Tools were to be found in plenty that the miners and quarriers and builders of old had used; and at such work the dwarves were still very skilled.

Normal sudoku rules apply.

Begin by transcribing the "Dragon" digits, from the previous puzzle.

Digits in "wall" (grey) cells are LARGER than digits in all orthogonally adjacent white cells.

Box borders divide the Running River (blue line) into segments that sum to the same value.

Digits in circles must appear in (at least) one of the four cells touching that circle.
