I would like to help you with your main problem, which you identify as
grafically making the 9 boxes coincide with the numerical pad on the right.

Since you did not state which compiler or operating system you are on,
I will assume that you are on DOS running gnat. Then the keys can be 
mapped as follows.

First, get keystrokes with the command text_io.get (ch), where
ch has been declared to be of type character. With the numerical
lock on, they keys map to the characters '1' through '9'. With the
numberical lock off the keys generate two bytes each, with the first
byte being binary zero. The second byte is as follows:

7 (home) gives 71
8 (up)   gives 72
9 (pgup) gives 73
4 (left) gives 75 
5 (mid)  gives 76
6 (rt)   gives 77 
1 (end)  gives 79
2 (down) gives 80
3 (pgdn) gives 81

To map them to the graphics you have chosen for the nine slots, use
an associative array or other data structure with similar functionality.

Hmmmm! I was once beaten at Tic Tac Toe by a chicken at the Santa Cruz
amusement park.  If a chicken can do it why is it so difficult?

While I'm here I'll tell another one.
In my nth language comparison meeting (where n is a large number) it
occurred to me to say that JAVA meant Just Another Variation of Ada.
People seemed to think it was funny, or maybe they just needed to laugh to
break the stress.

OK, but what is your problem ?
