Team Up. Level Up.

Red team versus blue team, staff-run so everybody knows the rules.

How It Works

Three steps and you’re in the game.

01
Gear Up

Grab a full-face mask and a blaster from the GellyBall staff. Red team on one side, blue team on the other. Masks stay on the whole time you're in the arena — no exceptions, and that's the entire safety briefing.

02
Load Up

Your blaster carries a hopper of hydrated gel balls on top — small, squishy, and 90% water. It's battery powered, so there's no pumping and no cocking. Point, pull, go.

03
Battle It Out

Inflatable bunkers give you cover across the field. Rounds are short and fast, so nobody sits out long. Gel balls burst on contact and dry up on their own — no paint, no scrubbing, no ruined shirts.

For The Grown-Ups

Safe, non-toxic,and mess-free.

GellyBall was designed from the ground up to be the lowest-impact option in the blaster-sport family. If your kid is too young for paintball and bored of foam darts, this is the gap it fills.

One honest caveat worth knowing: hydrated gel balls expand in water and are a choking hazard for toddlers. Keep loose gel balls away from very young children, and check with the on-site staff for the minimum play age that day.

Masks Provided

Full-face protection for every player, required in the arena. Spectators near the field should wear the eye protection offered too.

90% Water

Biodegradable and non-toxic, with no paint or dye. Nothing to scrub off skin, clothes, or the grass.

Lower Impact

Very low pressure — a hit reads as a light snap, not a bruise. Noticeably gentler than paintball or airsoft.

Staff-Run

Big Time Fun Company runs every round, hands out the gear, and enforces the rules so parents can actually relax.

The Zone

What it looks like in real life.

Questions

Before you gear up.

What actually is GellyBall?+

It's a lower-impact blaster game. You get a battery-powered blaster loaded with small gel balls, a full-face mask, and a field full of inflatable bunkers to hide behind. Think of it as the friendly middle ground between a Nerf war and paintball.

Does it hurt?+

Not really. The blasters shoot at very low pressure, so a hit lands somewhere around the snap of a rubber band — and most of that is soaked up by clothing. It's specifically designed to be lower-impact than paintball or airsoft, which is why it works for younger kids.

Will it stain my kid's clothes?+

No. GellyBalls are about 90% water, biodegradable, and non-toxic, with no paint or dye in them at all. They burst on impact and the little bit left behind dries up and disappears. No laundry drama.

What ages can play?+

It's built for all ages, and grown-ups are genuinely welcome to jump in. Very young children are typically kept out of live play — the hydrated gel balls are a choking hazard for toddlers, so keep them out of little hands and mouths. Check with the GellyBall staff on-site for the exact minimum age that day.

Do I need to bring anything?+

No. Blasters, gel balls, and masks are all provided at the GellyBall tent. Just wear closed-toe shoes and clothes you can run around in.

Do spectators need eye protection?+

Anyone standing near the field should wear the eye protection offered by the staff. Stray gel balls do occasionally leave the arena, and a mask is a lot more comfortable than a surprise.

How much does it cost, and how long is a session?+

GellyBall is run by Big Time Fun Company, so pricing and round length are set at their tent. Head to the GellyBall Zone when you arrive and they'll get you sorted.

Can I book GellyBall for my own party or event?+

Yes — Big Time Fun Company brings the whole setup to birthdays, festivals, corporate events, and schools. Their booking details are at the bottom of this page.
