3x3 Mini Lines
- Thermometers
- Region sum lines
- Whisper lines
- Modular lines
- Renban lines
The brief
Normal Sudoku rules do not apply.
Place the digits from 1-9 in the grid so that they do not repeat in any row or column. Digits can (and will) repeat in each 3x3 box. Each box will use exactly 3 of the digits from 1-9.
Digits cannot repeat on any lines
German Whisper Lines: Consecutive digits along the green German whispers line must differ by at least 5.
Renban: Digits along the purple renban lines must be a set of consecutive, non-repeating digits (in any order).
Modular Lines: Every 3 consecutive cells along a teal modular line must contain a complete set of residuals modulo 3. i.e: one from (3,6,9), one from (1,4,7) and one from (2,5,8).
Region Sum Lines: Box borders divide each blue line into segments with the same sum. Different lines may have different sums.
Entropic Lines: Every 3 consecutive cells along each tan line must contain a low digit (1,2,3), middle digit (4,5,6) and high digit (7,8,9).
Thermometer: Digits must increase along a thermometer starting at the bulb end.
