Join us at http://www.sudoku.com. • This video is intended for beginners who are still learning more about the game of Sudoku and would like to see kind of a visual discussion of the rules of the game. Sudoku is a game of logic. It's a game of deductive reasoning. It's a game of figuring out which numbers go in which spaces on the grid. As you can see, the Sudoku grid is made up of nine by nine squares. So a total of 81 spaces. • Within this grid, within these 81 spaces, there are rows that go from left to right. There are columns, which are the vertical sections. Then there are squares, which you can see denoted within borders. So these are the three basic sections or segments of the grid that you have to be concerned about when you're playing Sudoku. • Within each row, the numbers 1 through 9 appear, numbers 1 through 9 in the nine spaces. Within each column, the numbers 1 through 9 appear, and within each square, the numbers 1 through 9 appear. Your goal in Sudoku is to place the numbers on the grid without repeating any of those numbers, 1 through 9, anywhere within a row or column or square. • So, for example, if we look at this top row, there are already seven numbers placed. Right? There are only two blank spaces remaining. We've already placed, you know, just starting out, we already see that the numbers 1, 2, 3, 4, 5, 7, and 9 have been placed. So that means that these two blank spaces have to contain . . . Just by simple process of elimination, these two blank spaces have to contain the numbers 6 and 8. • Just by the rules of the game, we know that the number 6 and 8 cannot appear more than once within the same square or column. So that's how we can use the rules of Sudoku to identify which number goes in which space. We know we need a 6, we know we need an 8 in these two spaces. We see a number 6 right here within this vertical column. So that means that this blank space at the top cannot contain the number 6. So instead, the 6 has to go over here. That means, just by process of elimination, there's only one blank space left in this top row and only one number left to fill the space, and that would be the number 8. • To make sure we're on the right track, we can click 'check solution' right here on the left. There's a button that says 'check solution'. When you click 'check solution', both of the numbers we just placed on the board are in green. So we know we're on the right track. • The simplest rule of Sudoku is that you can't replace any numbers, 1 through 9. You can't repeat any numbers 1 through 9 within a row or column or square. You just have to kind of use that simple guidance to determine your strategy, your deductive pattern of thought as you move throughout the puzzle. • A strong recommendation in Sudoku is that you shouldn't try to guess which numbers go where. Because you might be tempted when you're trying to solve a Sudoku puzzle to randomly assign a number to a space. Or if you're trying to choose between two numbers, either one of which could potentially go into a blank space, you might be tempted to guess and just say, Oh. I can't figure it out. So I'm going to say that the 3 goes there, and the 5 goes there. Leave it at that. • But the problem with that is you might be wrong. If you guess wrong in Sudoku, putting the wrong number in the wrong space can set you off down the wrong path that's going to lead to, you know, failing to correctly place any other numbers. It might, you know, prevent you from solving the puzzle altogether. So instead of guessing, again, it's not really a rule per se, but you're very strongly encouraged to just keep thinking through the puzzle. Keep analyzing your options every step of the way, and keep ruling out certain numbers that you know can't go in each space. Then over time, the puzzle, you know, more and more of the puzzle will reveal itself. • Sudoku is a deceptively complicated game. The rules of the game are really quite simple, but the variations on the game, the number of possible combinations of numbers within these 81 spaces on the grid is nearly infinite. There's just a nearly infinite variety of possible Sudoku games that could be generated. • Every single time you play, you're going to see a different combination of numbers, different numbers that are already provided to you, different numbers that are still hidden, different clues that you have to analyze, different patterns to spot, different opportunities to uncover. That's what makes the game so much fun, so devilishly challenging, is that it's always something different. • You take this simple premise, nine numbers, one grid, one rule, and you can turn it into one of the most popular and beloved and fascinating logic games in the world. We hope you will enjoy many fun and happy games of Sudoku.
