Fifteen: A Game of Strategy

Fifteen: A Game of Strategy is a two-player game. The players take turns picking a number between 1 and 9. The goal is to reach a total of 15 using three of your collected numbers. The player plays against the computer.

In essence the game is identical to tic-tac-toe, but with a different mathematical way of looking at it. Placing the nine numbers in a three-by-three grid using the rules of a magic square would allow the player to employ the same logic as they would in a normal game of tic-tac-toe.
