What they will play

A world built from a book: walk the map and the characters ask the questions. This one is a real book, playable now.

How a homeschool classroom works

The parent uploads and shares; the learners play.

01

Upload what you teach from

A chapter of the curriculum, a history, a science text, your own notes: any PDF or EPUB up to 50 MB, in any language.

02

Make a classroom and add the worlds

A classroom holds up to 50 worlds and 200 members. Learners join with a link or a code, each with their own account, and play the same worlds with their own progress.

03

Follow along

The members list shows each learner’s level, day streak and progress per world, so you know which chapter needs another pass. Wrong questions come back to them on their own.

Why it fits a homeschool

The books you chose, the games they want, one payment.

Your curriculum, not a catalogue

The questions are written from the books you chose, in their language, so the game follows your plan instead of a publisher’s.

One payment, free learners

Lifetime Pro is a single payment for the parent, with 3 book-to-game credits included; the learners’ accounts are free. No subscription per child.

Five ways to review

The RPG, the tower, flashcards, mini-games and duels between siblings, all on the same questions, so review never looks the same twice.

Progress you can see

Levels, bosses beaten and progress in every mode per world, plus achievements and a day streak that reward showing up.

What it is not

Three things to know before you start.

For learners under 13

The service is not directed at children under 13, and each learner needs their own account, so it fits homeschoolers of secondary-school age.

Workbooks and worksheets

A scanned workbook has no text to read, and maths problem sets are better done on paper. It works on books and notes written in sentences.

A printable

There is no export to paper or to a form. The questions live in the games and the flashcard deck, where the learners answer them.

Built on real books

Live numbers, straight from the database.

Questions

Does it work with the books we already use?
Yes, as long as you have them as a PDF or an EPUB up to 50 MB with real text: a publisher’s PDF, a DRM-free EPUB, a public-domain book, your own notes. A Kindle or Apple Books file is locked and cannot be uploaded, and a scanned page needs a text layer.
How old do my kids have to be?
The service is not directed at children under 13, and every learner plays from their own account. It suits homeschoolers of secondary-school age, who read textbooks written in sentences.
Do my kids need to pay?
No. Learners join a classroom free and play its worlds in full. The parent who creates the classroom needs Lifetime Pro, one payment that includes the book-to-game credits for your own uploads. The public book worlds are free for everyone.
Can I see what they got wrong?
You see each learner’s level, the bosses they beat, their progress in every mode and their day streak, per world. The questions they got wrong come back to them on their own, in rematches, boss fights and the flashcard deck, until they get them right.
Can several kids share one account?
No. Progress, levels and the questions to repeat are saved per account, so two learners on one account would overwrite each other. Each learner needs their own free account, joined to the classroom with the same link.
Can they play without me?
Yes. Once a world is in the classroom it stays there, and the public book worlds are open to everyone. The games run in the browser on a laptop, a tablet or a phone, and in the Android app.
Is it free?
Playing is free: the public worlds cost nothing and never expire, and every premium world has a preview (5 battles, 10 Tower Climb questions and 10 mini-game questions, plus the flashcards of its first maps). Your own book takes a book-to-game credit; Lifetime Pro is one payment that includes 3 book-to-game credits and opens every world in full. No subscription.
