Whispering Pentominoes
- Whisper lines
The brief
Normal sudoku rules apply.
The indicated 60-cell white region contains one each of the twelve standard pentominoes (no repeats by rotation or reflection).
The green line loops through all twelve pentominoes. It passes through exactly 2 cells of a pentomino before visiting the next. Adjacent digits along the green line differ by at least 5. Also, each pentomino contains one of the 2-cell thermometers, whose digits must increase starting from the bulb end.
The arrangement of pentominoes must be deduced.
Once placed, each pentomino behaves like a 5-cell killer cage: digits do not repeat and must sum to the value listed at the thermometer bulb.
