The First Five Fives

Sandwich - Killer - Palindrome - Sudoku - where all clues are 20.


1. Normal sudoku rules apply.

2. one of the boxes is oddly friendly, in which each digit must match its square index in that box.

3. in cages, numbers sum to the clue in the top left corner - numbers can repeat in cages.

4. numbers outside the grid are sandwich clues (they indicate the sum of digit's between 1 and 9 in their column) - and they are closer to the 9 side.

5. the gray lines are palindromes (must be read the same from both ends) and all numbers on a palindrome must be repeated.
(correct) (124421) (444)
(wrong) (12421)

6. each main diagonal must be formed of exactly 5 different numbers - numbers can repeat.
