- Thermometers
- Modular lines
- Thermo
The brief
- Normal Sudoku rules apply. - Along Thermos digits must strictly increase from the bulb to the tip. - Any set of three sequential cells along a teal Modular Line must contain a complete set of residues modulo 3, i.e. one digit from {1,4,7}, one from {2,5,8}, and one from {3,6,9}. Digits may repeat on a line if allowed by other rules. - Each thermometer is also a modular line running from bulb to tip. Thermometers extending from the same bulb are distinct modular lines; that is, modular lines do not necessarily cross over bulbs from one thermometer to the next.
