Intro about the game: Sudoku is a puzzle game from Japan. It's one of my favorite logic games. If you need a game that make you think, this will be your game. The game can be challenging, and quiet addictive. Try this one by yourself, and feel its sensation. You won't regret playing this game. Purpose of the game: The aim of the game is to fill out the puzzle so that the numbers 1 to 9 appear only once in each row, column and 3x3 square. Let see how quickly you can fill the board. If you can't legally place that number in that position, you will hear a buzzer and be shown why. How to play: It is simple to control the game. Select the number to add from the bar at the bottom of the screen. Then click on the blank tile where you want to place that number. You can also select the number using the cursors, or the numbers 1 to 9 keys. If you want to remove a number that you have misplaced, simply click on that tile again with the same number selected. Special tricks: Fill out any square that have only one possibility number to be add on it, first. That will be your main key to solve the game. You can also place a 'note' in a tile by holding down 'Space' while you click. This can be used to note possible choices for that tile.
