Noder Runner

Normal Sudoku rules apply.

The digits along each arrow must sum to the digit in the circled cell. Digits may repeat along an arrow if permitted by other rules.

A black dot between cells indicates cell values with a 2:1 ratio. A white dot between cells indicates cells with consecutive values. Not all dots are shown.

Circled digits where four cells meet must be present as values in those four cells.
