That's Three in the DNA
- Whisper lines
- Renban lines
- Odd and even cells
The brief
Standard sudoku rules apply: each row, column, and 3x3 box must contain all the digits from 1 to 9.
Green lines are Whispers lines: adjacent digits connected by a green line must have a difference of at least 5.
Purple lines are Renban lines: each line contains a non-repeating set of consecutive digits in any order.
The grey circle is an odd digit. The grey square is an even digit.
