How does Thermo Sudoku work? Each sudoku grid contains thermometer shapes (often drawn to create themes) and digits on thermometers must increase as one moves further from the bulb end.
Miracle Sudoku features beautiful puzzles that at first glance look impossible to solve!! Indeed, some of our Miracle puzzles have as few as two givens digits (!) but you will find them all to be solvable with a bit of clever logic!
