About

Tired of playing Tic-Tac-Toe? Want something a little more challenging? Connect Four is a great game that fuses the complexity of a larger game board and the need to line up more pieces. In this project, you will create a version of the game with a graphical user interface that you can run on your computer. You will practice concepts frequently tested in technical interviews at top tech companies.

Make the cells in a column respond as a unit to fill the board from the bottom row.

Add an algorithm to check for a winner after every click and then highlight the winning cells.
