1. Normal sudoku rules apply.
2. The digit in an arrow cell shows the distance to a cell containing the same value as the box number. Each row, column and 3x3 box contains exactly one of these cells with the same value as its box number. Example: if r4c3 is a 5 then r9c3 contains 7, 7 because this is the box number. If r3c6 is a 2 then the arrow in r3c3 contains a 3.
3. Cells separated by knights move in chess cannot contain the same digits.
4. Cells separated by a white dot are consecutive. The central cell in each box experiences a negative constraint. If there is no white dot between the central cell and one of its 4 orthogonal neighbours, they cannot be consecutive.
