Normal Sudoku rules apply. Each row, column and 3x3 box contains each number from 1 to 9 exactly once.
The white dots represent a difference of 1 between two neighbouring cells. NOT all possible white dots are indicated; a.k.a. no negative constraint.
The grey squares are even numbers.
Note: One of the grey squares is not necessary for the solve, it is in the grid only because of symmetry.
The puzzle is also available online.
Lösungscode: Column 2 and Column 8
