I created these Sudoku puzzles and step-by-step guides for my daughter to help her learn the logical reasoning behind every single move. Key Features: 1 Step-by-Step Guidance: Uses visual aids to explain the logic behind each filled number, making the reasoning easier to grasp and remember. 2 Targeted Practice: Each difficulty level is designed around a specific solving technique that is guaranteed to be used in the puzzle, making it ideal for focused training. I hope you enjoy it! If you have any suggestions for improvement, feel free to email me at xlwrn50x@hotmail.com (screenshots are greatly appreciated!).
