Friendly competition, maximum fun, zero training required.
Channel your inner Olympian (minus the pressure and sweat) with a backyard tournament packed with laughs.

Here are some extra ideas: mix physical games with trivia, food challenges, or a 'create your own sport' contest. See who can come up with the most fun and absurd event.
3. Inflatable Adventure
Backyard bounce houses aren’t just for kids.
From obstacle courses to giant slides and inflatable jousting... There are tons of inflatable rentals ready for adults who want to jump, race, and bounce their way through a birthday bash. Add music, drinks, and a leaderboard for the most epic wipeouts. Part fitness, part ridiculous fun—and totally unforgettable.
4. Beer Pong Tournament
Raise your red cup and your competitive spirit.
Turn your backyard into a beer pong arena with multiple tables, brackets, team names, and a sick playlist.
Make it official with referees, custom cups, and tongue-in-cheek prizes for the winners. For a healthier twist, swap in themed drinks or non-alcoholic options to keep it inclusive.
5. DIY Recess Party
Dodgeball, kickball, four square — recess is back.
Set up a few playground-style stations in your backyard or a local park. Add some orange slices and Capri Suns for the full old-school twist.
6. Game Show Night
Bring the drama with your own version of Family Feud or Jeopardy.
Use a projector or TV screen, pick a host, and get teams buzzing in. You can even add a physical challenge round to your game night or turn wrong answers into dares.
Want to keep it minimal? Kahoot’s platform is a great way to organize group trivia with your phones.
7. Scavenger Hunt Showdown
Turn your birthday into a city-wide adventure.
Split into teams and race against the clock to solve clues, snap creative photos, and tackle wacky challenges. Whether you roam your neighborhood, a favorite park, or downtown, it’s the perfect mix of exploration and friendly competition.
You can DIY it with an app, or work with an event pro like Throwback. We'll design a custom hunt packed with trivia, GPS check-ins, and surprises that keep your friends and family laughing from start to finish.
8. Attend a Music Festival (or Concert)
Celebrate with live music and large crowd energy.
If your birthday lines up with a festival, grab your crew and make it part of the plan. Prefer something more low-key? Book concert tickets instead. Nothing like the shared energy of live music.
9. Outdoor Movie Night
Project your favorite movie in the backyard.
Add lawn chairs, string lights, and popcorn. Make it more social by mixing in some trivia or a movie drinking game.
10. Amusement Park Day
Because roller coasters make everything better.
Celebrate like a kid with a full day of thrill rides, arcade games, and funnel cake. Whether it’s a Six Flags park or a local fair, it’s a carefree way to spend time with friends and get your adrenaline fix.
11. Private Cooking Class (At Home or Out)
Level up your party with hands-on culinary fun.
Hire a local chef to come to your house and lead a group cooking lesson. Or, head to a nearby cooking school for a private class. From pasta-making to sushi-rolling, it’s a fun, social activity that ends with a delicious meal. Perfect for foodies or anyone who wants to try something new together.
12. Super Soaker Showdown
Cool off and unleash your inner kid.
Nothing says summer birthday like a full-on water battle. Arm everyone with water blasters (or upgrade to Super Soakers), set up refill stations, and let the chaos begin. Add team objectives like capture-the-flag or last-person-standing to make it even more competitive. Just don’t forget towels — and maybe a dry change of clothes for the afterparty.
