Marco Polo is a game that is played in a swimming pool or on another place with defined borders like a basketball court. 

You must have 2 or more players to play. One person is "IT."

All the players including "IT" must stay in the pool or within designated area.

The object of the game is for "IT" to tag any one of the other players. "IT" must keep his or her eyes closed during the game.

To help find other players, "IT" can say, "Marco." The other players must respond with the word "Polo." "IT" must try to tag someone by listening to the other players saying "Polo." 

When "IT" finally tags a player, the player who is tagged becomes the new "IT."
