Tic Tac Toe

Installation

php ./composer.phar install

Game start

php bin/app.php

Customization

By default, there are four classic cell combinations to win: horizontal, vertical and diagonal (left up, right down + left down, right up).

There is also a bonus combination added, which wins the game as well:

| X |   | X |
-------------
|   |   |   |
-------------
|   | X |   |

You can add any winning combinations to GameStateConstraint in bin/app.php as same as customizing the playing field/board size when the game starts.

Winning combinations have relative coordinates and are not linked with the actual playing field coordinates directly.

There playing field can be, say, 10x10 but still the winning coordinates should be put in the smallest rectangle possible.

The following winning combination

|   |   | X |
-------------
|   | X |   |
-------------
| X |   |   |
-------------
|   | X |   |
-------------
|   |   | X |

should be described as (x, y):

new CoordinateCollection(
    new Coordinate(3, 1),
    new Coordinate(2, 2),
    new Coordinate(1, 3),
    new Coordinate(2, 4),
    new Coordinate(3, 5),
)

which will make it work in any position within the actual playing field:

|   |   |   |   |   |   |
-------------------------
|   |   |   |   |   |   |
-------------------------
|   |   |   | X |   |   |
-------------------------
|   |   | X |   |   |   |
-------------------------
|   | X |   |   |   |   |
-------------------------
|   |   | X |   |   |   |
-------------------------
|   |   |   | X |   |   |
-------------------------
|   |   |   |   |   |   |

or

|   |   |   |   |   | X |   |   |

|   |   |   |   | X |   |   |   |

|   |   |   | X |   |   |   |   |
