Thermo Sudoku adds thermometer paths where digits must increase from bulb to tip. The normal Sudoku rules still apply, but every thermometer creates additional restrictions.
Yes. Row, column and box logic remain important, but you also need to think about the order of digits along each thermometer.
The bulb is the starting point of the sequence and often has the strongest restrictions, making it a useful place to begin the solve.
Longer thermometers restrict the range of values available to each position, often creating useful deductions before the rest of the grid is resolved.
Renban Sudoku, Palindrome Sudoku, German Whispers Sudoku and Dutch Whispers Sudoku are natural next steps if you enjoy line-based logic.
