Printable Sudoku Puzzles - Rules of Sudoku

Here's a summary of the rules of sudoku, in case you've never played before or need a refresher.

The rules are quite simple, actually. The hard part lies in solving the puzzle!

A sudoku puzzle consists of a 9 by 9 grid. This grid is subdivided into nine 3 x 3 boxes.

Some of the cells in the grid are prefilled with a number between 1 and 9, while many other cells are blank. Your job is to determine the correct number to be entered in each of the empty cells.

To figure out which number between 1 and 9 belongs in a particular cell, you need to adhere to the following rules:

  • The numbers 1 through 9 must appear exactly once in each row.

  • The numbers 1 through 9 must appear exactly once in each column.

  • The numbers 1 through 9 must appear exactly once in each 3x3 box.

The challenge of sudoku is using the process of elimination and other strategies to identify the unique solution for the sudoku puzzle. Sudoku really is an excellent brain game, as it trains logical reasoning and visual perception, among other brain skills.

Sudoku is my favorite logic puzzle. I have a hand-held Sudoku game (with stylus) that I play all the time.

Even though I practice, I'm not very good. But it's a great brain workout anyway. Anything that stretches your mind will help keep your brain sharp.

GAME TIP #1: Many games on this site such as Curveball were built with Adobe Flash. To play these games, you must allow the free Adobe Flash Player to run in your browser. If you don't see an animation in the red rectangle above, click in the red rectangle and activate your Flash Player. Then the Flash-based games should open for you.

If you see a message that the Adobe Flash Player is "blocked", go to your browser's Settings page and change Block to Ask First, if possible.

If the red rectangle is empty, your browser might not have the Flash Player. To check this, follow the steps on Adobe's Flash Player Help page.

GAME TIP #2: If you cannot get the Flash-based brain games to work, try the HTML5 brain games instead. HTML5 games do not use the Adobe Flash Player. They work in modern browsers automatically. All the HTML5 games are listed on this page.
