FOG Sudoku is a fantastic free online Sudoku game which is designed to make you feel like you are actually holding a pen in your hands and filling the puzzle in a newspaper. When the game loads, a newspaper unfolds and the game is brought into focus; this is after you have selected the difficulty level that you would like to play. The cursor in the game is a pencil, and all you have to do is click in a box with the pencil and then input the number. Once you have clicked on the box, it will turn a shade of green. When it does, simply select the number on your keyboard. When you type the number, the pencil will write it in the box all by itself. If you want to erase a number, select the ERASER button at the bottom of the game; the pencil will turn upside down and you can now erase the number. The eraser will erase the number in the same motions that you would use if you were doing the puzzle on paper. The fantastic animations aside, you have to remember that the game is about filling in the 3X3 grid with the numbers 1 to 9 and then making sure that the rows and columns also have the same numbers; in both cases the numbers should not be repeated. This is a game that allows you to scribble some notes on the notepad that is right next to the game. This is a great feature if you would like to put some suggestions as to which numbers should go to which place. This is a free online Sudoku game like no other and you will enjoy every minute of it. This game is just as addicting as those which you find in newspapers, so keep your alarm handy so as to keep track of time.
