I’m so happy I found the “Sudoku Professor.” He has helped me tremendously with just the first level of classes. I’m especially happy to have learned the “row and column elimination” technique. Where it used to take me hours to do even simple puzzles, I can now do them in minutes. Before the professor’s lessons, I was writing in all of the possible numbers to figure out the puzzle, but now I can see the answers with just writing in a few numbers. Thank you, thank you, thank you. I am a satisfied customer!
