As far as college and NBA is concerned, there is no limit as to the number of overtimes that can be played before determining a winner of the game.
Because the leaders of the NCAA decided that no game would end in a tie. If the game is still tied after one overtime, the teams will play as many overtimes as it takes to break the tie and declare a winner.

Until such time that there is a game winner, the game will continue via overtime.
If the organizing authority (tournament or league) determines that a winner must be determined, and the score is tied at the end of regulation, then two more overtimes of 15 minutes each are played. If, after both overtimes are played, the score is still tied then the winner is determined by kicks from the mark.
