Many people like to play the puzzle, Sudoku. You have to fill in the blanks with the numbers 1 to 9, so that the number does not repeat in any row, colum or box (3X3 squares).
There are many patterns of Sudoku puzzles.
I have created my pattern of the Sudoku puzzles, and have marketed them under the name Logic9. The pocketbooks are available in several bookstores.
Vol 1 to 4 of the Logic9 puzzles have a special feature. All the puzzles have a unique answer and can be solved by a logical approach (using my 3 tips). There is no need to guess.
Many people enjoy my Logic9 puzzles, because of this special feature.
