Renban Sudoku Snack
- Renban lines
- Palindromes
- Little killers
The brief
Normal irregular 7x7 Sudoku rules apply, i.e. each row, column and region has to contain the digits from 1 to 7. Each purple line contains a set of consecutive non-repeating digits in any order. The digits on the gray line form a palindrome, i.e. the string reads the same forwards and backwards. On the marked diagonal digits sum to the little killer clue outside the grid. (If there is no conflict with other rules, digits on the diagonal may repeat.)
