Well Vegas and gambling are pretty American, you could always do card games like poker and black jack. But that would be more Vegas themed than American themed I suppose. Don't rule out board games, I am 21 and still get a kick out of playing games with my buddies. You could do something like pictionary, or sharades. My favorite is a game called telestrations. It will have you and your friends cracking up all night, it is set up for 7 or 8 people, but you can always buy a second or third set to accommodate the extra people. Search it and see what ya think.

Good luck and have a fun party!

Another thought is Soda Pong, like beer pong but with soda instead, although it is normally a drinking game, so I would check with your parents before you do that.

American games like Baseball and Basketball , or maybe flag (or touch) Football (American football )

Outdoor party games like horseshoe tossing, Volleyball, Frisbee throwing, Hot Potato, Seven minutes in heaven if you have a closet or a shed.

American Pop Culture Trivia, Twister board game, American music trivia where each person sings a popular song by an American singer then everyone tries to guess who sings it,.

Make a bunch of questions about a your favorites...............so a person picks then reads a question like "what is my favorite color" then everyone takes turns guessing, you can be as embarrassing as you want to be .

Mia, what is it with you girls and games. She is turning 15 not 5, you are young ladies, young teens. I would think theme, think 70's maybe the Disco, Rock N Roll scene.

Time you started to learn to live kid. Once you get 15 year olds Rockin, food and plenty to drink, soda wise, and a good DJ, that's what is going to make the party rock.

Think about the culture of America (food, entertainment, holidays, music) and embed that into your plans. Go out for hamburgers. Have a dance party and play all American jams.

Okay, my friend is having her 15th birthday party which is American themed. I have googled and googled all night, but have only found some good answers. I have the whole food/decoration part down, however I need help with any games for us to play. Whenever I search online the games are for 1st graders and younger, please help me. I want anything you think would make her party a success. Thanks !!
