Tic-tac-toe

I looked up the word "Tic-tac-toe" up on www.wordreference.com, and there was a forum on what this game is called in Spanish. This is what I learned:
-In Spain, they call it "tres en raya"
-In Argentina, they say "ta-te-ti"
-In Mexico, it is "gato" (a tie is also called "gato" in Mexico)
-In Colombia, "triqui"

Who knew there were so many names?

As for the game, you put a subject pronoun in each one of the boxes in the grid. Students play in partners. One partner has one verb, and the other partner has a different verb. They write the correct form of the verb in each box. Just like in tic-tac-toe, the person who was three in a row, wins.
