Parents & teachers

Made for kids. Built with grown‑ups in mind.

Short, game-shaped lessons on real school topics, inside a site we keep deliberately simple and private.

  • No email, ever

    Accounts are a username and a password. We never ask for an email or a phone number.

  • Friendly names only

    Every username passes a kid-safe word filter before it can appear on a board.

  • No chat, no strangers

    There is no chat and no messaging. Other players only ever see a username and an avatar.

  • No ads, no trackers

    No third-party scripts of any kind and nothing to buy. The site only ever loads its own files.

  • Delete in one step

    Removing an account from the profile deletes it together with every saved game.

  • Real school topics

    Adding up to fractions, living things to forces. Short, levelled lessons kids can replay.

FAQ

Good questions.

Still curious? Write to us and a real person will answer.

Is ArxDa really free?

Yes. Every game is free to play, right in the browser. There are no ads, no in-game purchases, nothing to download and no app store.

Which ages are the games for?

ArxDa Math suits ages 5 to 11, ArxDa Moto and ArxDa Archer 6 and up, and ArxDa Science and ArxDa Air Force 7 and up. Slingshot Scholars is a physics puzzle for anyone who likes a challenge.

Do kids need an account to play?

No. Anyone can play as a guest, and progress saves on that device. A free ArxDa account adds cloud saves, ArxDa XP and leaderboards across every game.

What do you ask for at sign-up?

Only a username and a password. No email address, no phone number and no real name.

What is ArxDa XP?

Points earned in every game: lessons in Math and Science, rides in Moto, flights in Air Force, rounds in Archer and new stars in Slingshot Scholars. XP raises a player’s ArxDa level and ranks them on the weekly and all-time leaderboards. A daily limit keeps it fair.

Can I install ArxDa like an app?

Yes. Add ArxDa to your home screen from the browser menu, and every game opens full screen, just like an app.

Which devices work?

Phones, tablets and computers with an up-to-date browser such as Chrome, Safari, Edge or Firefox. Touch and mouse both work.
