The Connect 4 puzzle is familiar to everyone who likes these tasks. But this game is different from the rest of it similar to the fact that you can play not only alone, competing in wits with the computer, but also with a real rival. The one who wins the fastest of his chips is a line of four round elements. The line can be horizontal, vertical or diagonal. The moves are made alternately and here everything depends on which of the players will be able to distract the close attention of the opponent, and in the meantime put out their winning combination. Do not give the opponent the slightest chance whether it's a virtual or real player.
