Mobile GellyBall

Veteran Owned

Chicagoland and surrounding suburbs

Ages 5 and up!

We also offer Nerf!

No staining or mess

The Perfect Option for Younger Players as there is virtually No Sting!

Fun Operating Base use GellyBall Blasters. GellyBall Blasters shoot a soft gel ball, much like an Orbeez that your kids probably already play with! Shot from easy-to-use Blasters, the soft GellyBalls bounce off kids or simply disintegrate, leaving no stain, mess or sting. With Nerf guns players just have to reload with ammo off the floor, which make both options great for the younger crowd of ages 5 and up!

games you can play

Fun Operating Base

There is one starting point on each side. If you get shot anywhere on your body or your mask, you are out. Walk to the referee. When the game is over, the GellyBall teams will switch sides and play again.

Each GellyBall team will set up on their respective side. The goal is to get to the flag in the center and get it to your starting point – without getting shot. If you get shot, drop the flag . It is returned to the center by the referee and you are out. Play until one team wins, then switch sides.

This will be a timed event. Each team will take turns searching for a lost item, while the opposite team hides and defends the item. Whoever has the best time or has the most survivors left at the end of play wins.

Last man or team standing wins. Something like fortnite.

One person is unarmed and has to be lead across the field to other side (and not get shot).

Each person will take turns shooting at targets while being timed. Which team has the best time wins. 

There are two starting points that are opposite of each other. If you get shot, call yourself out and with your gun up, walk to your starting point, touch it and restart! Keep doing that until you are out of ammo.

This game pits one GellyBall player against another one. These two play each other, then winners play winners, until there is only one winner left.


Everything you need to know about GellyBall Parties!

GellyBall is an ultra low impact sport – suitable for kids age six and up. It uses GellyBall blasters – an easy-to-use gun that doesn’t use much pressure to shoot GellyBalls.  A GellyBall Blaster holds 750 shots without reloading!!! Lots more fun!!!

The GellyBall Blasters are electronic guns, so if you squeeze the trigger and hold it, they will shoot about 10 balls per second! However, we tell the players to shoot in “bursts” – just a quick pull on the trigger. The pod that holds the ammo is called a “Hand Grenade” – it holds 750 GellyBalls. The GellyBall Blaster accurately shoots a distance of 100 feet!

The GellyBall Blaster shoots GellyBalls!  A GellyBall is like an Orbeez. GellyBalls are teeny tiny absorbent polymer beads that expand into small beads when soaked in water.  They are biodegradable and nontoxic. They will not hurt your pets, plants or grass. Unlike paintballs that explode upon impact, GellyBalls simply bounce off or disintegrate – then they dehydrate!  No stain, no mess! 

Not Sure… How long does a glass of wine last? It’s really all up to the individual. GellyBall Blasters are electronic guns, so if you squeeze the trigger and hold it, they will shoot about 10 balls a second! But we tell the players to shoot in “Bursts” just a quick pulls on the trigger. That being said, we have found that the average group goes through 1,500 GellyBalls each in about a 2 hour party.

The GellyBall Blaster uses very low pressure to shoot, so it only feels like a good snap of a rubber band. But you’ll be having so much fun, you won’t even notice! 

It’s all the fun and excitement of paintball, without the pain and mess! Like paintball, you get to play all kinds of different games.

GellyBall beads are non-toxic, non-staining and biodegradable. They are safe for pets, yards and people! They are water-hydrated and will shrink to a tiny size before disintegrating entirely – no mess, no clean-up!
