Thermo Sudoku

About

Thermo Sudoku is a puzzle game that adds a twist to classic number grids. Instead of just filling cells, you arrange digits along thermometer shapes where values rise from the bulb end. Each grid follows standard Sudoku rules but layers in these thermometers, forcing you to balance multiple constraints at once. The result is a cerebral challenge that feels familiar yet oddly fresh. Players praise its clever use of visual logic and the way it pushes beyond traditional Sudoku patterns. With a 4.5/5 rating on puzzle forums, it’s a favorite among fans seeking deeper problem-solving. Available on PC, Mac, and mobile since 2020, it offers a no-frills single-player experience that’s easy to start but tough to master.
