Sudoku Tiles is an interesting free online Sudoku game. It has a 3D feeling, and the whole grid looks like it has been carved out of a wooden board. When you want to put a number in a slot, you simply drag the number from the pad on the right and drop it where you want. You continue doing this according to the rules of Sudoku. You have to fill every 3X3 grid with the numbers 1 to 9 without repeating any of them. Similarly the numbers 1 to 9 should not be repeated in the rows and columns of the main 9X9 grid. The game also allows you to practice the penciling method by using what they call temporary markers. You can only use as many markers as there are in the game. There are various puzzles in the game and you get to select the one you want to play using the arrows in the main menu. Once you are through with the puzzle, you can check the puzzle by clicking on the button at the top of the game; you can only use the button when the puzzle is complete. If you use it before, you will get a very loud warning telling you to stop cheating. When you have completed the puzzle and you want to check the puzzle, you will get a magnifying glass which you will drag across the whole puzzle. All the tiles which are wrong will be highlighted with a red color. The aim is to make sure that when you check the game, you will not have any red tiles; that is when you will know that you have successfully filled in the puzzle. If you like a novelty Sudoku game, then this is the best game to play; you get to feel like you are actually doing something with your hands and not just your mind.
