The player's goal is to arrange four pieces of their color in a row in a horizontal, vertical, or diagonal row to win.
Rule:
Each player chooses a color and takes all the pieces of that color, then the turn is alternated between the two.
During your turn, you drop a piece of your color onto one of the 7 columns of the vertical chessboard, letting it fall freely until it hits the bottom or another piece. Then pass the turn to the next person.
Be the winner!
