Entropic Zigzag
- XV and number dots
- Entropic lines
- Little killers
The brief
Normal Sudoku rules apply. The orange lines are entropy lines, that is, any set of three consecutive digits on such a line must contain a low digit (1, 2 or 3), a medium digit (4, 5 or 6) and a high digit (7, 8 or 9). Digits on a marked diagonal sum to the clue next to the arrow. (If there is no conflict with other rules, digits may repeat on a diagonal.) Digits connected by an X sum to 10. (Not all Xs are given)
