Game 2: Connect 4

The Connect 4 game was designed in the 1970s by David Wexler. His desire to create a “vertical” game led him to invent Connect 4. Read about how the game was created here.

Connect 4 is a two-player game similar to Tic-Tac-Toe. It is played on a 6 x 7 grid (with 6 rows and 7 columns). Players choose a color, and take turn dropping their colored chips from the top row down a column. The first player to get four chips in a row (vertical, horizontal, or diagonal) wins!
