Puzzle types of every hue,
Signs and pictures give a clue,
Letters, numbers, symbols, too,
Help your brain go solving thru
Number puzzles have been around for at least a couple hundred years. Some appeared in French newspapers in the late 19th Century when French puzzle setters began experimenting with removing numbers from "magic squares." Reportedly, the newspaper La France, printed a puzzle in 1886 that was almost a modern Sudoku.
According to Wikipedia, Howard Garns, a 74-year-old retired architect, most likely designed the modern Sudoku anonymously. It was first published in 1979 by Dell Magazines as Number Place, the earliest known examples of modern Sudoku. Nikoli introduced the puzzle in Japan in April of 1984 in the paper Monthly Nikolist. Since then, variations abound. There is something for everyone, almost, although not everyone likes this type of Brain-Aerobic Exercise. If it's not your cup of tea, there's plenty of other ways to stimulate and challenge your brain.
