- Whisper lines
- Palindromes
The brief
Normal Sudoku rules apply. Numbers on green lines are at least 5 apart from their neighbors on the line. Numbers may repeat on green lines, if other rules allow. Numbers on orange lines are a palindrome, in the same sequence forward and backward. Numbers with an X between them sum to 10. Numbers with black dots between them are in a ratio of 2:1. Not all possible X and dots are given.
