If you enjoy Sudoku variants with a strong visual and logical element, you'll love this Thermo Sudoku. The classic rules form the foundation, but the grid features distinct thermometer shapes. The key rule is that along each thermometer, the digits must rise continuously from the bulb (the lowest temperature) to the tip (the highest). This constraint creates a powerful series of relationships between cells, making it a favorite among solvers. This particular puzzle is part of our Fun With Sudoku Series and offers an excellent, enjoyable challenge. Grab your pencil, study the thermometers, and enjoy this popular puzzle.
