Startup Screen

On startup you will see a Java window similar to that shown below.

Selecting A Square

You must select a square to input and delete numbers. To select a square, click on it with your mouse. The square will change colors from white to cyan.

If you'd like to select somewhere else, click that square with your mouse or use your arrow keys to move one space in the direction you've indicated.

Entering Numbers

Enter numbers with the number keys on your keyboard. Pushing most of the other keys on your keyboard will not affect the program, however some keys have special actions attached to them.

Entering Memo Numbers

Use memo numbers when you need to remember what numbers are possible for a certain square. You may enter up to four memo numbers per square.

In order to enter memo numbers either:

Click one of the four corners of the square, or
Hold down the appropriate memo number key ("a," "s," "z," "x")

The memo number keys are listed below

a	upper-left corner
s	upper-right corner
z	lower-left corner
x	lower-right corner

Enter the numbers themselves as you would normally in a square--using your keyboard's number keys. Press the return key to turn the whole square cyan and return to normal number entry mode.

Deleting Numbers

Delete a number from a square by pressing either the "0" (zero) key or space bar.

Check Your Answers

You may check your answers once you have filled in the entire game board. The program will not automatically check if your answer is correct, please push the Check button at the top of the game board.

If you have repeated a number horizontally, vertically, or in a 3 x 3 block, the checker will turn the numbers red. Please note that you will not be able to enter data while the errors are displayed in red. Press the Check button one more time to return to data entry mode.

If you have answered the puzzle correctly, the program will display a congratulatory message screen.

Clear

If you would like to delete all of your answers from the game board and start over, push the Clear button. When you push the Clear button, the program will display the following confirmation message.

If you press the clear button again, all of the data you have entered will be cleared from the game board. Push cancel to return to the game without deleting your data.

Those are the functions available in the Java Puzzle Collection.
