FOR PARENTS

Practice that doesn't feel like practice

Not a game. Not a worksheet. CAT4, 11+ and KS2 SATs style practice wearing a retro-arcade coat, so your child shows up for the practice underneath.

Educational value

Designed alongside the school cognitive ability tests, but written so the practice itself is the reward.

CAT4, 11+ and KS2 SATs in one place: The four CAT4 reasoning areas, the 11+ verbal staples, and KS2 SATs maths and English. 39 skill areas. Pin to one exam style, or let the app blend them.
Story cases and a city that grows: For children who need a story, not a scoreboard. Signal Hunts wrap the same questions in detective cases that can never be failed, and every correct answer anywhere relights a district of their own Circuit City.
Adapts to your child: Set their year group once. Difficulty climbs as they unlock rings, the picker leans toward whatever they've found hard recently, and the timer ramps from none to exam pacing only when they're ready.
Paper-structured mock tests + diagnostic: Four papers to sit properly: CAT4 Full Battery, 11+ GL-style, SATs Arithmetic, SATs Reasoning. Plus a 26-minute diagnostic that gives you a baseline. Each ends with a per-skill breakdown.
Built-in tutor content + worked solutions: Every skill has a plain-language guide, and a wrong answer always shows why. Not just a mark. Which matters most for the children who find being wrong hard.
Visibility for parents: Strengths, weak spots, and a CAT4-style report card with SAS / NPR / Stanine once there's enough data. Mock results feed the same trend line. Exactly what your child sees. Never a different story.

Your child’s moment

The bit your kid does first

Before any practice happens, your child picks an avatar. Colour, kind of character, accessories. It’s a small thing, but it turns the app from “another worksheet” into “mine”. The customisation grows as they earn coins; new themes unlock as they progress through the rings.

Want to show your child? Send them puzzitron.com/kids: a retro-arcade-look landing pitched at them, with the puzzles in motion. They’ll still need you to set up the account first.

Safety & trust

We’ve set this up the way we’d want our own children’s data handled.

No ads, ever: Not now, not in the paid tier, not in any future version.
No trackers where it matters: Zero analytics, no pixels, no advertising SDKs on the part your child uses. Marketing-page visits are measured; the child-facing app never is.
Data stays in the EU: Hosted on UK / EU infrastructure with the database in Frankfurt. We don't sell or share child data with anyone.
Children's Code aligned: Designed around the ICO's Age Appropriate Design Code: minimum data, clear privacy info, no dark patterns, no profiling.

Designed for different brains

Puzzitron follows WCAG cognitive-accessibility guidance and ships with an opt-in Calm Mode for kids who find busy interfaces, timers, or sharp failure cues overwhelming. ADHD-friendly by design, useful for any child who finds practice apps loud.

What Calm Mode does

A parent toggles it on per child from the dashboard. Defaults across the app shift:

Reduced motion and a calmer palette. The arcade still works, it just stops shouting.
Untimed practice by default. The exam-pacing ramp is a separate opt-in.
Configurable session length (5 / 10 / 15 / 20 minutes) with a visible countdown and a movement-break prompt at the end.
Neutral failure language and cumulative-only progress: no streak-loss, no buzzers, no shame copy.

What Puzzitron is not

Puzzitron is a reasoning-practice tool with an ADHD-friendly accessibility mode. It is not a medical device. It does not diagnose, treat, or screen for ADHD or any other condition. If you’re worried about your child’s attention or learning, please speak to your GP or have a look at:

Frequently asked

The questions we get most. Anything missing? Email hello@puzzitron.com.

Is Puzzitron free?: Free to start, and free for as long as you want it. One child can use Puzzitron free for as long as you like, with every skill area, 20 questions a day and no card. Puzzitron Plus adds unlimited practice, every mock paper and the full parent report for up to 5 children, from £6.99 a month, or £59 for a 12-month pass paid once. There is no trial clock. Tutors have their own plan.
Is Calm Mode free? Will the ADHD features be paywalled?: Yes. Calm Mode and the ADHD-supportive accessibility features are free on every plan, now and for good. We will not charge for accessibility. Puzzitron Plus pays for unlimited daily practice, every mock paper and the full parent report; Calm Mode is the same whichever plan you are on.
Is this the real CAT4, 11+ or SATs test?: No. Puzzitron is a private practice game using the same style of reasoning, maths, and English questions that show up in CAT4, 11+, and KS2 SATs exams, but it's not affiliated with any exam board or assessment provider. Performance on Puzzitron isn't a predictor of real exam outcomes. It's there to give your child confident, low-pressure practice.
What ages is it for?: Designed for ages 7–11 (Year 3 through Year 7 in the UK system). Set your child's year group on their settings page and the picker biases toward year-appropriate content. Difficulty ramps as your child progresses; the timer ramps from no-timer to real exam pacing automatically. Adults can override either at any time.
What about my child's data?: We collect the minimum needed for the app to work: first name, a globally-unique handle (three random words like tiger.river.galaxy), a bcrypt-hashed PIN, and practice history. No third-party trackers or advertising scripts ever load on the part of Puzzitron your child uses. UK/EU-hosted, deletable on request, ICO Children's Code aligned. Full detail on the privacy page.
How does sign-in work?: Adults sign in via a magic email link. No password to forget. Your child gets their own handle + 4-digit PIN that they tap on a shuffled animal keypad, so an over-the-shoulder watcher can't memorise the digits.
We work with a tutor. Can they use Puzzitron with my child?: Yes. A tutor can set your child up themselves and send you a handover link when you want the account in your own name, or you can add your child and share progress from your dashboard. Tutors can choose up to six skills for your child to concentrate on, which are pinned at the top of their practice screen, and they see the same readiness report you do. You can remove a tutor from your child's settings at any time.
Can I delete everything?: Yes. From your dashboard you can soft-delete a child profile (30-day restore window) or hard-delete your whole account, which removes every session, attempt, flag, and the account row itself. Database backups retain a copy for up to 30 days then it's all gone.
