# What is Extreme Sudoku?

4. Practice Visualization: train your mind to visualize the implications of placing a certain number in a particular cell. This skill can help you anticipate potential conflicts or patterns that may emerge later in the puzzle
5. Stay Organized: Keep your solving process organized and systematic. Avoid making random guesses and ensure that each step you take is based on logical deductions and patterns.
