Playing cards, sports, spelling bees, or solving puzzles is always fun! Senior centers offer all kinds of puzzles including Sudoku’s. They are a Godsend to seniors who are limited in what they can do, and can be bored to death. The Manager of a nearby Merrill gardens bought 4 copies of Stars In Sudoku Land, and held a class to teach the residents the Thomas Sudoku System. She said Sudoku’s are tops in cognitive benefits. This is the third Edition. Once you get the hang of my Thomas Sudoku System, the price is well worth the money. You will be a Star In Sudoku Land!! My book takes the reader through a sample easy puzzle, step by step, with an answer sheet to check your entries. My numbering system is unique and helps in keeping track of choices for possible numbers. The ¾ 4 4 concept system, is one of 4 shortcuts in solving very difficult puzzles. They are of course part of the copyrighted paperback book. This paperback also makes a great gift, for older folks to pass the time productively and win! But people love to work on puzzles while flying, or traveling for business or pleasure too. If you are wondering what to give to your Grand Kids, Stars In Sudoku Land makes a great gift for 5th grade through college graduates. Teachers use Sudokus for bright students who get bored to death waiting for others to finish an assignment. They are naturally curious and like challenges. I hope you enjoy this paperback as much as I have wanted to teach others and share it. This is my Dream! Marvin Haley Thomas (Buz Thomas)
