Claim:
A Sudoku puzzle solving apparatus comprising: a substantially flat panel having, means of forming eighty-one areas of substantially equal size, wherein said areas are arranged in a square pattern of nine rows and nine columns, wherein each one of the rows has nine of said areas, and each one of said columns has nine of said areas, and wherein, each one of said areas comprises a means of forming nine substantially equal subareas, wherein each of the subareas of each one of said areas comprise a means of showing on them all the nine digits of one through nine in the manner of one digit in one subarea and further in a non-repeating manner of said showing of said digits in said area, and said apparatus further comprising; means to set to no display status any of said digits from at display status, and means reset from said no display status of said digits back to at display status, each one of said areas is provided underneath said area with means of illuminating nine separate subareas individually, and with means of shutting off of said means of illuminating individually, whereby, said sudoku puzzle can be solved, by following the rules of sudoku and with the help of said apparatus in the following manner, when the space directly above each one of said subareas of each one of said areas is occupied by a single digit chosen from the single digits of one through nine in the manner that in any one subarea of said areas, any chosen digit appears only once, by setting all of said subareas initially illuminated to make each digit occupying the space above each one of said subareas visible, and followed by, shutting off of said means of illuminating in eight subareas, in each one of said areas that matches in position to said sudoku puzzle's corresponding initially given solution number's position on said sudoku puzzle, wherein said shutting off, results in the remainder of one illuminated subarea in each one of said areas containing eight subareas having shut off of said means of illuminating, and thereby results in the illumination of only one digit that matches with its corresponding initial solution given number in value on said sudoku puzzle, and further followed by, logically continuing the shutting off of the remainder of illuminated regions in the manner required for said sudoku puzzle's solutions by evaluating for non solution illuminated digits in every one of said subareas of said areas in said sudoku puzzle, until every one of said areas remains with only one digit illuminated.
