Connect Four game. Additionally, form a square with 4 corners instead of a line.

Connect Square

From wikipedia: Connect Four:

Connect Four is a game in which the players choose a color and then take turns dropping colored tokens into a six-row, seven-column vertically suspended grid. The pieces fall straight down, occupying the lowest available space within the column. The objective of the game is to be the first to form a horizontal, vertical, or diagonal line of four of one's own tokens.

As a twist, this TUI implementation also offers two more variations of the game:

• form a square, i.e. four cells forming 90 degree angles and equidistant from each other
• form a line or square
