Gomoku

Gomoku is a terminal implementation of a classic match-5 game played on a
19×19 Go board. Players take turns to place pieces one at a time on the board.
Similar to tic-tac-toe or ‘connect-4’, the objective is to make a unbroken
line of five pieces, either horizontally, vertically, or diagonally anywhere
on the board.

Moves are entered by typing the desired coordinate for the piece. The game can
be played against the computer, against another player, or by pitting the
computer against itself.
