4 In A Row as the game suggests is the same as the game with the name Connect Four.  Players take it in turns chosing a column to drop their colour disk into the top and see if they can outwit their opponent and get four in a row of their colour.

This can also be used as a tie breaker.

Another option :- The game allows a random drop too so questions could be asked.  If the question is answered correctly then the player can choose where the token is dropped and if answered wrong the random button is pressed.
