At Flip Side Ninja Park, we offer a birthday party experience like no other facility in Northwest Arkansas can.

Your Birthday Ninja and friends get a chance to train like real ninja warriors! (1.5hrs total) After parking all of the presents in your private party room, your ninjas will get 60 minutes of open gym time with a party host to help guide them through obstacles. After their time on the floor is up, you'll have an additional 30 minutes in our private party room for cake and presents with all set-up and clean-up done by Flip Side staff so you don't have to worry about anything but enjoying your time. Check out the packages below to see which works best for your party. We can't wait to help you celebrate! It's going to be a ton of fun!

What to expect: We'll try and take the stress out of your party prep! Our staff will decorate and set up everything for your party before everyone arrives. Our certified ninja coach/party host will help guide the ninjas around open gym and assist with any additional party needs. Open gym capacity (30) will be reduced by the number of participants from the birthday party. *Please note* Our party room is upstairs and we would be more than happy make handicap accommodations upon request.

We'll provide: Set-up and clean-up of the party necessities. This includes: cups, plates, utensils, and decorations. (We will do blue/red ninja warrior themed decorations). All you have to bring is the food and refreshments!

Do spectators count towards the pricing?

Spectators do not count towards the participant pricing. Parents, Grandma, etc. can go around and take pictures of the party while the kids play. Anyone wishing to join in on the obstacle fun will be included in the participant count. (The birthday ninjas parents do not count towards this number and are encouraged to play)

Can we bring our own decorations?

We'd love to allow everyone to come in and set up, but due to time constraints (to allow everyone more party and gym time!), we only have 20 minutes to break down, clean up, and decorate for the next party. You can bring some small, personalized items, but please plan on us providing the majority of your décor.

What ages are allowed to participate?

Due to liability reasons, we can only allow children ages 5 and up to participate in activities on the gym floor on their own.

Does everyone need a waiver?

Minor waivers or Adult Waivers are REQUIRED for every person participating in the gym activities
