Carô is Vietnamese version of Tic Tac Toe with unlimited board and 5 in a straight line to win.

Carô is as easy to learn as Tic Tac Toe but as hard to master as Chess. The unlimited board makes it even more challenging because you can play until one wins (no draw).

This is my first shot at introducing a popular pen-and-paper game we played everyday when we were in school in Vietnam so please give feedbacks. Free and no ads.
