Normal sudoku rules apply.

Cells seen a kings move apart in chess must not contain the same digit.

Digits on a white dot must be consecutive.

Blue cells are row indexers. For example, if r1c1 was a 5 then r5c1 would be a 1.

Red cells are column indexers. For example, if r3c1 was a 5 then r3c5 would be a 1.

Not all dots are necessarily given.
