To play

• Clone, cd into the root dir, and run the "main" script: $ ./oxo
• Your machine should have Bash 4+, preferably Bash 4.4+ (latest stable)
• Be kind to the "Computer player". It is randumb :D

To code-read

• Board design and setup is at the beginning of oxo_logic.sh

• The scoring logic is based on pattern matches against a regularly-formatted board. See:

  • The linchpin function fit_board_to_square_grid
  • The commentary in the # SCORING LOGIC section
  • The scoring functions, particularly __all_crosses, __all_noughts, __player_wins_grid, crosses_win, noughts_win, and its_a_draw

• I like to write Functional Programming style Bash.

• Follow the commit history to trace how the game logic gradually emerged.

But why?!?

For unabashed mirth and merriment, of course. Why else?
