Normal Sudoku Rules apply
Starbattle: Two of the digits act like stars: they cannot touch each other (or themselves), even diagonally. Which of the two digits act like stars, has to be deduced.
3D-Sandwich: Numbers (or sums) sandwiched between two stars (horizontally, vertically and diagonally!) have to be divisible by the sum of the sandwiching stars.
Arrow: Digits along an arrow sum to the number in the circle
Solution code: Enter the digits of row 4 (left to right) and col 9 (top to bottom)
