Connect 4 has been a classic for some time now. It's definitely a game that will not go away anytime soon. It's similar to Tic Tac Toe, but in this you slide tokens down a column and are trying to get four in a row before your opponent does. So, while you're trying to get 4, you also have to prevent your opponent from getting four so keep your eyes peeled for some tricky situations.
