Oil, Water, Extenban
- Killer cages
- Renban lines
- Oil and water cages
The brief
Normal sudoku rules apply.
Each cage is either full of "oil" (even digits), full of "water" (odd digits), or a mix of both. In all cases, each "row" within a cage is of just one type (oil or water). Oil floats on water, so even digits will always be in rows above odd digits in mixed cages.
Digits in cages do not repeat.
Digits in cages must sum to the small clue, if given.
Digits along a pink line form a consecutive group in any order. Digits do not repeat on the line EXCEPT for the ends, which are the SAME digit. For example, possible fills for a line of length 4 might be 6456, 7867, 1231, etc.
