The program was originally designed to create a 10 * 10 grid of sorted numbers with no duplicates, similar to the example on the right, however, every game will be different.
When I decided to make it into a game, I added a Menu with 2 items.
The 1st item says "Game Size".   It allows the player to select a size from 1 of the following:   3*3, 5*5, 7*7, 10*10 or 25*25.
The 2nd item says "New Game".   It, surprisingly enough, starts a New Game.
The red bar at the top of the screen says "Click on Number", then the current number.   It flashes between red and white.
The small box in the upper Right Hand corner is a timer.   It displays the number of seconds that the current game has been running.   The timer will not start until the player correctly clicks the lowest number.   Once started, the timer continues counting until the last number is correctly clicked.   When I say "correctly clicked", I mean that it has to be the number that is dispalayed in the red bar at the top of the screen.
