Instructions

Main Menu	The main menu has 5 features to choose from 3 Game Options Choose A Preset Puzzle     Allows You To Choose from a set of     predefined puzzles Enter Your Own Puzzle     Gives you a blank Sudoku Board for     you to enter a puzzle that you found     from any source. Generate A Random Puzzle     Randomly Generate a puzzle, giving     an infinite number of possible puzzles     with which to play. And 2 Configuration Options Options     Choose to play with or without sound,     and choose if you want to see what     numbers are possible in squares that     are not filled in. Load Game     Load a Game that you have     previously saved.
Difficulty Selection	Warm Ups     Really quite simple, here to help people who are just beginning to learn the basics of sudoku. Easy    Starting to get more difficult, will help train you on your way to becoming a sudoku grandmaster. Moderate     Getting pretty tricky. Still very solvable though even for a novice. Hard     Starting to get pretty complex. If you can solve these your skills are getting quite good. Brain Benders     Even for good players these can be quite tricky. Do not take these lightly. If you can solve them you are doing quite well. Grandmaster     Once you have mastered these. Sudoku Tutor can teach you nothing, you have achieved the highest level of sudoku enlightenment available. Try nuclear physics or quantum mechanics. Sudoku Tutor can no longer challenge you.
Choosing A Puzzle  At A Difficulty	Once you have chosen a difficulty you will be asked to choose from among 20 puzzles at that difficulty to solve. The ones that have a check beside them mean that you have already solved them. Your first time none will be checked. Time is -  Minutes: Seconds Solver is - the number of times you used the solver while solving the puzzle. Ideally 0 or really it was Sudoku Tutor that solved the puzzle. Otherwise they will say 'NotSolved' and have a icon showing part of a sudoku board indicating you have not solved this puzzle.
Puzzle Entry	The third option in the Main Menu.    When you open the Puzzle Entry Main Menu Option, you will be presented with a blank puzzle like the one on the left. Use the keys on your phone up down left and right to move around on the puzzle. The currently selected square is denoted in gray. It starts in position [5,5], right in the middle. Press one of the number keys 1-9 to enter that number in the square. If you make a mistake you can de-enter a number using the 0 key. (Which you can also do while playing) Once you are finished entering the puzzle you found in the newspaper or some book switch Sudoku tutor into "playing" mode by pressing the 'Playing Key' (Left Menu Key). Thats really all there is to puzzle entry. Now you can solve the puzzle in your phone or have Sudoku Tutor teach you how to solve it by entering solver mode. (Same way you entered playing mode just choose solver now which should be where playing was in puzzle entry mode)
Options Menu	Options can be entered though either the main menu or through the in game menu by choosing options. The options are if you want sound effects or not. And if you want the possible numbers for every square to be showing. Sound effects you may want off when commuting to not disturb other people. The game may be too easy when showing possible solutions so I think you should only use this mode when you are stuck and need help but don't want Sudoku Tutor to just tell you the next square using the solver. Or you are learning. When you are finished with the options make sure you choose ok in the options menu to save your choices to your phones memory card.
Showing Possibles	Showing possibles is almost like using the Sudoku Tutor solver. Except instead of just telling you what number is next it will show you what numbers are possible in all unfilled squares. It does make puzzles very easy while learning but you should'nt use it when playing because it is sort of like cheating. For example in the puzzle on the left with the show possibles enabled it is easy to see that [5,1] = 7 [7,2] = 7 [9,3] = 3 [5,8] = 9 [9,8] = 1 And when you filled those you would see that [1,6] = 8 [8,1] = 5 [9,4] = 5 ..... And you see the puzzle is very easy when this is enabled.
Entering Rough Work	While in "Playing" mode. (Modes can be switched using the menus to one of, solver or playing, or you can be in entry mode by choosing enter your own puzzle from the main menu) Rough numbers may be entered only when in playing mode by pressing # - followed by the number you wish to enter. If you have made an error (like I sometimes do because phone keys are small) you can un-enter rough work by pressing # -  followed by the number you wish to un-enter. Of course to enter or unenter you need to have the selection box over the square you wish to effect. The current selection box is denoted by gray. You can move it around using the arrow keys. (While In Playing Mode)
Hints	While in "playing" mode. (Modes can be switched using the menus to one of, solver or playing, or you can be in entry mode by choosing enter your own puzzle from the main menu) You may ask for a hint by pressing the enter key (Key in the middle of all the arrow keys on your cell phones keypad). The effect of this will be to highlight in yellow all the values that are not possible in the selected square. In the example on the left [5,5] cannot be 1 because of [5,3] 8 because of [4,4] 3 because of [6,4] 4 because of [6,5] 7 because of [4,6] 6 because of [5,9] So I would then know it must be 2,5 or 9. Which I could enter as rough work if I wanted to. By pressing #-2,#-5,#-9.
Save /Load	While in "playing" mode. (Modes can be switched using the menus to one of, solver or playing, or you can be in entry mode by choosing enter your own puzzle from the main menu) You can save your game by choosing Save from the options menu. Which will call up a slot screen like the one on the top left. You choose what slot to save into and click the save menu option. This will take you back to the puzzle you were playing.  Make sure to select the puzzle using the enter key before clicking save so that the radio button has it highlighted. To load the game it is the fifth option in the main menu. It will pull up your fifty save slots and as you to choose a game. Highlight the game you want. Then click LOAD in the menu to load your save. Or "SAVE" if saving.

Solver (AKA Sudoku Tutor)

Confusion Warning : Once you enter solver mode. The only key that makes sense is the forward or right key. All other keys on the keypad will not do anything in this mode. To exit the mode and move around you will have to select "playing" from the menu. You can flip back and forth between solver and playing mode using the in game menu. Illustrated by the top left picture. One reason to switch back to playing while in solver mode is that you are not sure why an elimination was made and want to go to that square and get a hint. There are three types of eliminations that can happen when using the solver. The first is a simple elimination shown by the second picture on the left. This happens when there is a square with only one value possible in that square. If there are several squares like this they will all be filled in yellow at the same time and filled in one by one. The second type of elimination is a complex elimination. Denoted by he third picture down to the left. The yellow square is the one being filled in. While the green squares are squares that the number s not possible in leaving only the yellow square where that number is possible. Of course that leaves the "logic hole" of when there are no squares that have single values and no squares that can be automatically filled in because they are not possible elsewhere in the same column 3x3 square, or row. In this situation Solver/Sudoku Tutor makes a "guess" denoted in purple. illustrated in the fourth picture on the left. In this way sudoku tutor is able to solve any solvable sudoku puzzle. For a deeper illustration of how this works see either the Easy Puzzle Example or the Grandmaster Puzzle Solver example.
