The objective is to win the "big" board. To place your symbol on one of the cells a player must win the "small" game of that cell. Once completed the small board will be replaced by the corresponding symbol or in case of a draw an equals sign will be desplayed.

Rules

Both the small and big board's index are represented as so:

1|2|3
-+-+-
4|5|6
-+-+-
7|8|9

The first player will be assigned 'O'. They choose the board they choose to start from.

The players will place their symbol one after the other on the small boards. The place on the small board where a player places their symbol represents the place on the big board where the opponent will have to play. If a player places their symbol on the cell 1 then the next player will have to play on the 1st board. If a player places their symbol on the cell 5 the the next player will have to play on the center board.

Example: If player X plays on a cell 4, player O will have to play anywhere on the 4th board

Usage

To play the game first you'll need to compile the game using the Makefile provided. An executable named TicTacToe will be created generated. You can simply execute it to play 1v1 against another user.

A few flags can be specified:

• -p1 <input_methos>/-p2 <input_methos>: Change the input method for player 1/2.
  • player: Default input method that asks the user for the cell index.
  • first: Loads input method that chooses always the first possible cell to play on.
  • next: Loads input method that chooses always the cell who's index is one higher than it's last invocation.
  • random: Loads input method that chooses a random cell.
  • replay: Loads input method that reads from a log file and chooses the next valid play for the given player.
• -log <path>: Specify the path for the log file. Default log file is located at /tmp/TicTacToe.log.
• -no-log: Disable logging.
• -replay-file <path>: Specify the path for the replay file. Default replay file is set to the same as the default log file.
• -delay <milisecond>: Specify how long a "bot" takes to play. Defaults to 200 ms.
• -seed <number>: Specify seed to use for random input method. Defaults to a random seed based on current time.

Warning: If the same flag is given twice or conflicting flags are specified the last one will prevail and overwrite previous flags.
