Play, and learn to play Sudoku. From Rookie to Expert.

## What is this game? Which are the characteristics?

• This SUDOKU game has
1. a grid of 81 fields with 9 rows and 9 columns divided in 9 shapes and
2. 9 sign symbols.
• In the here presented Computer Aided Sudoku Game (SdkGame) the shapes are squares and the sign symbols numbers. For the playing some fields have numbers. They are the initial values.
• The game is terminated
1. if each field has a number and
2. each row, each column and each square has all the 9 numbers.
• During the game the cursor helps to choose a field, the keyboard to put a number into the field or erase it from them. Also, the game is absolutely similar to the game with paper, pencil and eraser.
• But the SdkGame has some Options and Utilities, they help the player to save the game after each step, to visualise step history eventual with additive information, to analyse a field, to search admissible values, to go back to an arbitrary chosen field.

## Whom is it advantageous for?

### For the Rookie

• The game history and the search utilities allow an ease entry in the game.
• To distinguish between thinking in field and thinking in value is not always a trivial thing: Someone can put a value into a field, but a field does not exist for a number which was until now not used concerning a row or a column or a square. The SdkGame is a useful means for them.
• The list of game steps with the additive information allows recapitulates the correctness the player's memory. Also, it is recommendable for memory training.

### For the Interested

• In general, the game stimulates the combination capability and is very good for memory training
• When playing SUDOKU the player might have to choose among two or more possibilities whithout being sure that his/her choice is a good one. A couple of steps later a contradiction may arise. In this case the player should be able to go back step by step and rub out the values filled in.

### For the expert

• In some cases there are more than one solution. To find all possible solutions is not an easy task. SdkGame features - if used - support the player in these cases.
• If someone searched and found one admissible value using the utility, he/she can easier find an explanation. But if he could not find a reasonable answer, he can download in the next future a new version of SdkGame, which can verbally give out the correct answer.
