Extreme Sudoku Puzzles – The Ultimate Test of Logic

Extreme Sudoku is for the absolute best solvers, removing up to 65 numbers from the grid. With so few clues, standard techniques won’t be enough—you’ll need deep pattern recognition and high-level solving methods like Forcing Chains and Nishio. These puzzles require intense concentration, making them one of the toughest logic challenges you can face.

Strategies to Conquer Extreme Sudoku Puzzles

Extreme Sudoku solvers rely on techniques like Forcing Chains, where you track multiple possibilities in a chain reaction to see which leads to a contradiction.Nishio is another approach where you assume a number placement and follow the logic—if it results in a contradiction, you know the assumption was wrong. These techniques require time and effort, but solving an Extreme Sudoku is one of the most satisfying achievements for a true Sudoku expert!
