sudoku got your number?
since april, when sudoku was introduced to the united states in the new york post, more than half the leading american newspapers have begun printing one or more sudoku a day. no puzzle has had such a fast introduction in newspapers since the crossword craze of 1924-25.
the craze started in england last november, when wayne gould, a retired judge from new zealand, persuaded the times of london to print the puzzle. judge gould had seen sudoku in a japanese puzzle magazine and written a computer program for creating sudoku at any desired level of difficulty.
japanese puzzle magazines are filled with novel and ingenious logic puzzles. they are as popular in japan as crosswords are in the united states. but judge gould saw two things in sudoku that set it apart: the rules, which can be stated in one sentence, and the size, which does not vary with degree of difficulty.
the audiences for crosswords and sudoku, understandably, overlap greatly, but there are differences, too. a crossword attracts a more literary person, while sudoku appeals to a keenly logical mind. some crossword enthusiasts turn up their noses at sudoku because they feel it lacks depth. a good crossword requires vocabulary, knowledge, mental flexibility and sometimes even a sense of humor to complete. it touches numerous areas of life and provides an "aha!" or two along the way. sudoku, on the other hand, is just a logical exercise, each one similar to the last.
the number of possible ways to fill a 9-by-9 sudoku grid is calculated at 6,670,903,752,021,072,936,960 - and the number of different ways to give starting digits for solving all these combinations is almost unfathomable.
i have been seeing this all over the news lately. it's apparently the newest rave. this puzzle is for the logical mind, so if you want to give it a shot then you can check it out here...
