Inside the game

Five worlds, with your child in the middle of the adventure.

Nobody loses: if they bump into something, they get up and keep going. Everything is spoken out loud, so kids who can't read yet can play on their own.

These are real screens from Junior's game. Play the demo on your phone.

How it works

We create the hero

We draw a character that looks like your child, with every move, and record the voice lines with their name in English.

How it started

I was tired of watching my son sit through ads instead of playing.

Junior is 4 and loves soccer, building bricks, dinosaurs and cars. He downloaded one game after another trying to find one to play. They were all the same: every level, every jump, every tap, another ad. He spent more time waiting for ads to end than playing.

So, after more than 30 years working in technology, I built a game for him myself: the hero is Junior, wearing his number 19 jersey, and a voice calls him by name. No ads at all. He loved it, and now I make the same for your child.

Questions

What parents usually ask.

How does the yearly plan work?

You pay once a year. During the year your child plays the full game and gets a new story every month with the same hero. There's no automatic renewal: 30 days before it ends, we email you so you can renew if you want.

What if I don't renew?

The game keeps working on your child's device just as it is. Only the new stories and updates stop.

Is the game in English?

Yes. Buttons, instructions and every voice line are in English, recorded with your child's name.

Do I need to download an app?

No. You get a link, open it in the browser and tap "Add to Home Screen". It becomes an icon and opens full screen, like an app.

Which devices does it work on?

Android phones and tablets, iPhone and iPad, and computers too. On a phone it can be played in portrait or landscape.

Does it work offline?

Yes. After opening it once with internet, the game is stored on the device and opens even in airplane mode, like on a road trip.

Can you use a cartoon character or my team's logo?

We don't use characters or brands that belong to other companies. We create an original hero that looks like your child, with the colors and jersey number they like.

Do I have to send a photo?

No. The description is enough. If you send a photo, it's only a reference for the drawing. The game uses the drawing, never the photo.

What ages is it for?

Ages 3 to 8. The controls are big, instructions are spoken, and nobody loses: if they bump into something, they get up and keep going.

Where are you based?

MJ Kids is a small studio in Brazil run by a dad. Your card statement may show the charge as MJ Kids, converted from US dollars by your bank if your card is in another currency.

Your child will want to play again. And you'll let them, for 20 minutes.
