How it works

Learning is play, not a quiz in a game costume

Your child drags, builds, sorts and solves problems with Soli. Every loop ends with a reward they can actually use back home.

  1. 1
    Take a quest

    Soli poses a problem inside the story of a subject world.

  2. 2
    Learn by doing

    Your child explores the idea with objects they can move, then practises in a mini-game.

  3. 3
    Clear the challenge

    Getting it wrong costs nothing. Soli shows it again and offers another way in.

  4. 4
    Go home and use the reward

    Items unlock new things to do with Soli — not just a new look.

↻ And the next loop begins

One Soli, one home, many worlds

Each subject has its own map and progression. Every reward comes back to the same home.

Your companion

Soli grows through learning. You cannot buy the shortcut

Friendship builds from learning, caring and playing. No plan shortens this road.

1
Star Sprout

Soli has just met your child — curious, and close by on every quest.

2
Little Star

New things to do together: high-fives, reading, playing ball.

3
Big Star

Taller, a deeper voice, and new rooms open up at home.

4
Radiant Star

Still ahead — your child will see it when they get close.

For parents

You see exactly which skills your child has mastered, not a score

  • ✓
    Real mastery, not a percentage correct

    We weigh accuracy, how much help was needed, consistency and transfer — mapped straight onto Cambridge learning objectives.

  • ✓
    Progress is never for sale

    We never sell stars, XP, mastery or learning items. Paying only widens how much they can learn and how much content they reach.

  • ✓
    You set the time limits

    Weekly goals, reminders and device limits are yours to decide. Your child never sees a price or a buy button.

Frequently asked questions

ScholarKin is for ages 6–12, matching Grades 1–5. The Placement Adventure finds the right starting point without feeling like a test.

No. The Learning Journey pauses, but your child can still play at home, explore freely and revise. Energy refills overnight.

No. School grade and subject level are kept apart. Children only ever see journey names like “Number Explorer — Chapter 3”, never a label suggesting they are behind.

Parents create a separate account per child, with no limit. Grade, Soli, progress, plan and courses all stay per child.

Scan the QR code you generate under Student profiles — single use, valid for five minutes. You can also print a login card with a fixed QR code.

No. Cancelling costs you no progress, no Soli, and none of the items your child earned.
