Diving Competition
- Killer cages
- Thermometers
- Whisper lines
The brief
Normal Sudoku rules apply. THERMOMETERS- Numbers on thermometers strictly increase from the bulb end. KILLER- Numbers in cages sum to the number in the top left corner of the cage. DUTCH WHISPERS- Numbers on red lines are at least 4 apart from their neighbors on the line. The blue line is the water, and has no effect on the puzzle.
