# Steve's 3D TicTacToe Player.

By Steve Baker <sjbaker1@airmail.net>

## Introduction.

TicTacToe - the worlds most boring game. Well, when played in three dimensions with a 4x4 board, this simple game takes on an entirely new level of intellectual challenge.

## Installation:

        ./configure
        make
        make install

If you are running Windoze or something that can't run configure scripts and makefiles, don't sweat it. There is just one C++ source file - no special options or libraries.

No, I won't provide a binary version, project files and such.

## License:

This program is offered under the terms of the GNU Public License (GPL).

## Instructions:

Run this from any shell:

        ttt3d

The computer takes 'O's and lets you go first. The first person to make a row of 4 wins.

    Where would you like to play your X ?
    [1..64]:

(In the example above, the computer just played in square 43 the asterisks help you see where he just played).

Imagine the four grids stacked on top of each other. (Either from left to right or right to left - it doesn't matter). You can form your row of four X's either within one layer - or across layers. Anything that would be a straight line in 3D. So in this example:

       |   |   |         |   |   |         |   |   |         |   |   |
     X |   |   |         |   |   |         |   | O |      *O*|   |   | X

       |   |   |         |   |   |         |   |   |         |   |   |
       | X |   |         |   |   |         |*O*|   |       X | O |   |
    _5_|___|_7_|_8_   21_|22_|23_|24_   37_|___|39_|40_   ___|___|55_|56_
       |   |   |         |   |   |         |   |   |         |   |   |
       |   |   |         |   |*O*|         |   |   |         | O | X | X
    _9_|10_|11_|12_   25_|26_|___|28_   41_|42_|43_|44_   57_|___|___|___
       |   |   |         |   |   |         |   |   |         |   |   |
     X |   |   |*O*      |   |   | X       |   |   |       O | X |   | O
       |14 |15 |      29 |30 |31 |      45 |46 |47 |48       |   |63 |

...the computer just won with a diagonal line (when someone wins, the winning line is highlighted with asterisks).

You'll find the computer is an extremely hard opponent to beat, but it CAN BE DONE!
