1. Gather a group of friends: Playing Marco Polo is a fun way to enjoy the swimming pool with your friends. Ensure that you have enough players to make the game exciting – typically, four or more players work best.

2. Choose who will be “it”: Select one player to start as “it”. This person is responsible for trying to tag the other players by using their senses rather than sight.

3. Establish the boundaries: Set the limits of the game area, typically within the pool itself. You may limit the playing area if your pool is large or if you have younger players involved.

4. Prep for safety: Ensure everyone playing knows how to swim and understands pool safety rules. Notify all participants that running around the pool or pushing others into the water is prohibited.

5. Put on blindfolds (optional): If desired, the person who is “it” can wear a blindfold – but this isn’t mandatory. The main rule is that they must keep their eyes closed during play.

6. Position “it” in the middle of the pool: Have “it” stand in the center with their eyes closed (or wearing a blindfold) before starting the game.

7. Begin the game: After counting down from three, “it” shouts “Marco,” which signals that they can begin their search for other players in the pool area.

8. Call out “Polo”: Upon hearing “Marco,” all other players must respond with “Polo,” enabling “it” to locate their position by sound alone.

9. Listen for movement: While other players shout “Polo,” they must also try to evade “it” without leaving the designated play area. In doing so, they might accidentally splash water or make noises that could give away their location to “it”.

10. Tagging: When “it” locates another player by sound, they attempt to tag that person. If successful, the tagged player becomes the new “it,” and the previous “it” now joins the rest of the players.

11. Repeat play: Continue playing in this manner until everyone has had a chance to be “it” or until you decide to stop. Be prepared for laughter, fun, and potential splashing as everyone enjoys this classic pool game!

Remember to always prioritize safety and fun while playing Marco Polo with your friends. It’s a great way to create lasting memories and build camaraderie at pool parties or summer gatherings!
