Connect 4 Program Python Dummies
Connect Four (or Four in a Row) is a two-player strategy game. Each player takes turns dropping a chip of his color into a column. The first player to align four chips wins. The Connect 4 game is a solved strategy game: the first player (Red) has a winning strategy allowing him to always win. OOP can make development faster, and your applications run faster.
