Your questions, answered

It's a free game on Roblox where every challenge is a real exam-style revision question.

• Players run along a track, and each gate is a question. Right answers speed them up.
• Good runs earn eggs, which hatch into collectable pets. Each pet comes with a fact from the lesson.
• There are short revision notes, hints, worked examples, and mini-games for skills like balancing equations, circuits and graphs.

GCSE: Biology, Chemistry and Physics (AQA and Edexcel, Foundation and Higher), English Literature (AQA), English Language (AQA, Edexcel and Eduqas), Drama (AQA) and History (AQA).

A-level: Psychology (AQA), with more subjects on the way.

Maths and OCR aren't covered yet.

Gradehatch is a small UK studio, building platforms with help from subject experts. We make revision feel like the games young people already play, without the parts of gaming parents worry about.

• Lessons are written with the help of AI tools and subject experts.
• Every lesson is then checked multiple times against the exam board's specification, in a separate review, before it goes into the game.
• Some lessons have also been reviewed by qualified teachers, and we're adding more.
• Community feedback constantly helps us improve our content. If you or your child spot something that could be better, please tell us.

If you spot a mistake, please tell us (see Contact). We fix errors quickly.

The game is built on two well-researched study methods: retrieval practice (testing yourself rather than rereading) and spaced repetition (coming back to things just before you'd forget them). Its study plan notices which questions your child finds hard and brings them back more often.

We don't claim it will raise grades. We'd rather show you evidence when we have it.

GCSE students (usually Years 9 to 11, ages 13 to 16) and A-level students (ages 16 to 18).

Roblox shows new games only to age-checked players aged 16 and over until Roblox has reviewed them for younger accounts. If the game isn't showing on your child's account yet, Roblox's Approved Experience parental control lets you allow this one game. That's entirely your decision (see Roblox's parental controls).

The game's Roblox maturity label is shown on its Roblox page. Here's what's behind it:

• The chase is cartoonish. A character (a wave, a cloud, a fox) chases the player. If it catches them, their character flops over and they answer a question to get back up. There's no fighting, no weapons and no blood.
• Set texts and History cover difficult themes, as the exam requires: Macbeth, An Inspector Calls, Blood Brothers, war poetry and some History topics deal with murder, suicide and war. We cover these in plain, factual text, with no images of violence or injury and no jokes about suffering.
• The Holocaust isn't covered in the game at present.
• Calm quiz mode turns any run into a simple quiz, without the chase.

We haven't built any chat, messaging or voice features. The only chat is Roblox's own, which Roblox controls, with age checks, filtering and age-based limits. You can turn chat off or limit it in Roblox's parental controls.

No. Players can't draw, write signs or post anything other players can see. The answers your child types are checked by the game and aren't shown to anyone else.

A Race lets up to 4 players in the same server answer the same quiz at the same time. Racers can't block or touch each other, and friends are invited with Roblox's own invite button.

No. We never send private messages to players, on Roblox or anywhere else, and we never ask a child for their real name, school, age, address, photo or phone number.

If anyone claiming to be from Gradehatch messages your child privately, it isn't us. Please report it to Roblox and tell us.

1. In Roblox: use the Report button (in the Roblox menu, or on the player's profile).
2. Tell us: email burdonmark@gmail.com with "Safety" in the subject. We read safety emails within 1 working day.
3. If a child is in immediate danger: call 999.
4. If you're worried about grooming or sexual abuse online: report to CEOP at ceop.police.uk.
5. NSPCC helpline for adults: 0808 800 5000.

Yes. Every lesson, question, quiz, note and study feature is free, and always will be.

Yes, there are optional extras: cosmetics, such as trails, auras and plot decorations, and a few small conveniences, such as an extra pet slot. They're bought with Robux through Roblox, and nobody needs them to learn or to enjoy the game.

• We will never sell learning: no paid lessons, hints, answers or quizzes.
• We will never sell luck: no paid eggs, no loot boxes and no boosts to the chance of a rare pet. Every egg is earned by answering questions, and the odds are shown.

Any purchase on Roblox uses Robux, Roblox's own currency. In Roblox's parental controls you can set a monthly spending limit and get spending notifications.

No. There are no adverts in the game. If we ever add optional adverts, they will never appear in lessons, never be needed to learn anything, and never be shown to under-13s.

Very little, by design. Roblox gives the game a numeric account ID and a username. We never receive names, email addresses, ages, locations or payment details.

Against that ID the game stores progress: pets and eggs, lessons completed, which questions were answered right or wrong (so the study plan can find weak spots), and settings. It's stored on Roblox's own servers. The game doesn't send it anywhere else.

Only Roblox's built-in analytics, which shows us totals, such as how many players finished their first lesson. We don't use outside trackers or advertising profiles, and we never sell data. This website has no tracking cookies and no analytics either.

Yes. Email burdonmark@gmail.com with your child's Roblox username (not their real name) and we'll delete their game progress. We also act on deletion requests passed to us by Roblox.

Our privacy policy has the full details, including who is responsible for the data and your rights.

• We avoid "you'll fail if…" messages.
• Missing a day never takes away pets, eggs or lessons. At most, a streak counter starts again.
• Calm quiz mode is always available.

Yes. An Inspector Calls is built around a young woman's death by suicide, and it's on the GCSE specification. We cover it factually, without method detail or images.
