An indoor activity they play on their feet

Rain outside, energy inside. Hopadoo turns the laptop, tablet or phone you already have into games kids play by moving, at home, at Grandma's or on holiday: they jump the hurdles, step into the lane with the right answer, and jump to pop letters into words. It's free, and there's nothing to install.

What they do

• Hopadoo: a jungle race. Jump the hurdles, step left and right to dodge the crates, grab the coins.
• Sum Run: a sum comes up on the sign, and each kid runs into the lane with the right answer. Adding and taking away up to 10.
• Word Pop: a picture word is missing a letter. Stand under the right letter and jump to pop it in.
• Monkey Mirror: the monkey strikes a pose. Copy it like a mirror and hold it, but don't copy the parrot!
• Sneak: tiptoe up to a sleeping tiger together, and when it peeks, freeze or hide as a tree or a rock. Part of the optional Family Unlock.
• Ten Jar: when a firefly glows above you, jump with your hands up to catch it for the jar. Part of the Family Unlock too.

How much room you need

About 3 by 3 metres: push the coffee table back. The kids stand 2 to 3 metres from the screen, side by side, and the kid on the left runs the left track. A bright room helps the camera see them.

For siblings, and for one

Two kids race side by side in Hopadoo and Sum Run, and team up in the others. One kid can play any of them alone.

Setting up takes two minutes

1. A laptop, tablet or phone with a camera. Prop a tablet or phone up sideways, on a shelf or against a few books.
2. Put it at about chest height, camera facing the room: a laptop on a table or TV stand, or a tablet or phone propped up sideways. A laptop plugged into the TV makes the runners easy to see.
3. Step back 2 to 3 metres: Player 1 on the left, Player 2 on the right, head to toe in view.
4. Hands up to join, and play.

Nothing leaves your device

There are no accounts or logins, no ads and no tracking. The camera video is processed on the device and never uploaded, so no video, photos or body data leave it.
