Less scrolling.
More jumping.

Hopadoo is a set of free browser games kids play by moving in front of the camera on a laptop, tablet or phone. They jump hurdles, dodge crates and run to the right answer with their whole body, and the runners on screen copy every move. Screen time on their feet, with nothing to install.

Why the camera? It’s how the runners copy each move, and the video never leaves this device.

The games

Pick a game.
Get moving.

They all run on the laptop, tablet or phone you already have, wherever you are. The kids move, and the camera does the rest.

Why Hopadoo

Same screen.
Different afternoon.

Kids are going to have screen time. Hopadoo makes it the kind where they're up on their feet, out of breath and laughing at each other.

“A fun alternative to mindless scrolling… FREE browser games that get kids up and moving… no downloads required!”

Donna Boucher, Math Coach’s Corner

An afternoon of scrolling

  • Sitting still
  • Thumbs only
  • Headphones in, on their own
  • A feed that never ends

An afternoon of Hopadoo

  • Jumping, dodging and racing
  • The whole body, not just thumbs
  • Side by side with a sibling, or with you
  • 60-second rounds with a finish line

How it works

Prop it up.
Kids up.

No console, no controllers, no downloads. A laptop, tablet or phone with a camera is everything you need, at home, at Grandma's or on holiday.

Prop it up

A laptop on a table, or a tablet or phone propped up sideways. Open hopadoo.com, press Play and allow the camera. That's the whole install.

Step back

Two kids side by side, 2 to 3 metres from the screen. The kid on the left runs the left track, the kid on the right runs the right.

Race!

Jump the hurdles, step sideways for coins. Rounds last 60 seconds. Most coins wins, then everyone demands a rematch.

The clever bit

Your kids are
the controller.

They move, and the runner copies. The camera finds shoulders, hips and feet many times a second, right on your device. No suits, no sensors and no controllers to lose down the back of the sofa.

  • JumpClears the hurdles.
  • Step left or rightDodges the crates and grabs the coins.
  • Raise a handCatches stars in no-jumping mode. Made for flats with neighbours downstairs.

Privacy

The camera
stays home.

Hopadoo works out where arms and legs are on your device, then throws each video frame away. We never see your kids, and we never want to.

No accounts, no ads, no tracking. Kids never see a price or a shop in the game, and buying anything will always sit behind a grown-ups-only button. Read the privacy policy.

What you need

You probably have
all of this already.

A laptop, tablet or phone Anything with a front camera. Prop a tablet or phone up sideways.
Some floor About 3 by 3 metres. Push the coffee table back.
Two kids Ages 5 to 12. Grown-ups are allowed, and will be out of breath.

Questions

Things parents ask us.

Where does the camera video go?

Nowhere. It's processed on your device and thrown away frame by frame. Nothing is recorded or uploaded.

Isn't this just more screen time?

It's screen time on their feet. They jump, dodge and race with their whole body, and rounds end after 60 seconds instead of an endless feed. We'd still rather they played outside when they can. Hopadoo is for rainy days and "I'm bored" afternoons.

Is it actually free?

Yes. Hopadoo, Sum Run, Word Pop and Monkey Mirror are free and stay free. Extra games like Sneak, Ten Jar, Word Hop and Number River come with the optional Family Unlock, one payment and no subscription. See pricing

What ages is it for?

About 5 to 12. The sums start at +1 and −1 and grow with each kid, up to sums within 20, and the words start with three letters.

How many kids can play at once?

One or two, side by side. Every game also works for one kid alone.

Do I need to make an account?

No. There are no accounts at all. If you ever buy the unlock, you get a key by email and that's it.

Will it work on a tablet or phone?

Yes. Prop it up sideways on a table or shelf, step back, and play. Phones and tablets work just like a laptop.

Who's behind this?

A small independent team. We read every email: hello@hopadoo.com
