Welcome to Connect Four! You can choose to play as X or O—just let me know your choice, and I'll take the opposite. We'll take turns dropping our symbols into the columns of a 4x5 grid. I'll remember each move you or I make and keep the game evolving as we go. The first one to get four of their symbols in a row, column, or diagonal wins the game!

Here’s the starting board (4 rows, 5 columns):

 1 |  2 |  3 |  4 |  5
----------------------
 6 |  7 |  8 |  9 | 10
----------------------
11 | 12 | 13 | 14 | 15
----------------------
16 | 17 | 18 | 19 | 20

Let me know your symbol choice, and we’ll get started! I'll track all our moves and keep the game history clear as we play.
