FOR PARENTS

Practice that doesn't feel like practice

Not a game. Not a worksheet. CAT4, 11+, and KS2 SATs style practice with a retro-arcade look and fun bits, 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
Verbal, quantitative, non-verbal, and spatial reasoning — the four CAT4 areas — plus the 11+ verbal-reasoning staples (synonyms, cloze, letter sequences, ciphers, anagrams, insert-a-letter, hidden words) and KS2 SATs maths + English (mental arithmetic, pre-algebra, word problems, reading comprehension, spelling, grammar & punctuation). 20 sub-tests total. Pin to one exam style or let the app blend.
Adapts to your child
Set your child's year group (Year 3–7) once and the picker biases toward year-appropriate content. Difficulty climbs as they unlock new rings; the picker biases toward weak and untouched areas using a recency window, so a tough week moves the needle immediately. The timer ramps from no-timer to real exam pacing once they're confident.
Paper-structured mock tests + diagnostic
Beyond the quick drills, your child can sit a real paper. Four presets today: CAT4 Full Battery, 11+ GL-style, SATs Arithmetic, SATs Reasoning. Plus a 26-minute Diagnostic that touches every skill and gives you a baseline you can compare against later. Each finishes with a per-skill breakdown and a suggested next practice.
Built-in tutor content + worked solutions
Every sub-test has a short “how to think about it” guide written in plain language. Wrong answers always show a step-through walkthrough — “your answer, the right answer, how to think about it next time” — not just a mark. Helps every kid; especially helpful for kids who find being wrong frustrating.
Visibility for parents
Clean dashboard shows top strengths, areas worth more practice, a CAT4-style report card with SAS / NPR / Stanine once enough data accumulates, and a suggested next-practice prompt. Mock-test results roll into the same trend line so progress builds over time. Same data the kid sees post-test — never contradictory commentary.

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
No third-party scripts on the part your child uses — the child-facing app has zero analytics, no Facebook pixel, no advertising SDKs. We measure marketing-page visits with Google's privacy-friendly ads measurement and never load it where children are.
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?
Yes — completely free during the beta. An enhanced paid version (one-off payment, no subscription) is on its way; the free tier won't be crippled and will stay free.
Is Calm Mode free? Will the ADHD features be paywalled?
Calm Mode and the ADHD-supportive accessibility features are free, now and forever. Charging for accessibility isn't something we're going to do. The paid tier will add extras like multiple child profiles, additional themes, long-form practice modes, and an opt-in Attention Gym (mini-games for exam-room focus practice) — but the core CAT4/11+ practice and Calm Mode stay free.
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.
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.

Ready to give it a try?

One-time email link to sign in — no password to remember. Your child has their own player code so you stay in control of the account.
