No doubt most of you have heard of sudoku, the print puzzle that is taking the publishing world by storm. In June 1972, I created my own unique adaptation of the old Chinese magic square that I called MagicNine back then. KOKONOTSU Super Sudoku evolved out of that. The rules for KOKONOTSU are basically the same as for ordinary sudoku except that we have added important 4 th and 5th dimensions: In addition to the rows, columns and boxes the two diagonals are to be filled in, and there is an invisible hidden Magic Puzzle Heart within the puzzle grid for clever players like you to discover and use for help in solving the puzzle.
Sudoku puzzles are known as number nine puzzles, and Kokonotsu is a nine-letter Japanese word that means simply nine. KOKONOTSU is actually older than sudoku. It is based on the ancient Chinese magic device known as the Lo Shu Square. As many of you know, this is a mathematical number grid dating back to 2200 B.C. that symbolized the natural order and harmony of the Universe. Later variations were the "Magic Squares" and "Latin Squares" rediscovered by the Swiss mathematician Leonhard Euler in the 18th Century.
