Choose the cadet, then Parent Settings at the bottom of their base, and answer the grown-up maths question. Each cadet has their own settings.

In Parent Settings, use Times tables focus and tap the tables you want. They lead every alien wave and fill the Training Simulator. Leave them all off to follow the school year.

In Parent Settings, each topic has its own switch. They’re on from Year 1 by default. Beside each switch, use − and + to move that topic a year easier or harder than the child’s school year. When a topic is on, one of the three missions offered each time is about it, and it appears in the Training Simulator.

Both are in Parent Settings. The Earth region sets the school-year names, the currency in money questions, how clock times are written and the spelling. It starts from your device’s region. Levels line up by school year, so UK Year 3 gets the same content as US Grade 3.

It’s for Year 4 and up, and it’s set up like the Multiplication Tables Check that Year 4 pupils in England take each June: 25 questions from the 2 to 12 times tables, 6 seconds for each, a short pause between them, and the score at the end. As in the real check, questions aren’t read aloud. Outside the UK it’s called the Times Tables Challenge. It’s free, and the answers count towards your child’s progress.

Yes. In Parent Settings, under Answering, choose Tap an answer. You can also switch counting pictures on or off. Reception starts with tapping and pictures; everyone else starts with the number pad.

Both are under Audio & Reading in Parent Settings. Reading aloud uses your device’s own voice. If nothing is spoken, check the device’s volume and that an English voice is installed in its accessibility or speech settings.

At the top of Parent Settings. Once a week, after some play, a “weekly report is ready” card also appears on the cadet’s base, behind the grown-up question. The headline numbers and trickiest facts are free. Premium adds the times tables grid, the weekly summary, Times Tables Check scores with the facts that were slow, progress by topic, and sharing the report as text.

Open Parent Settings, then Backup & Restore, and choose Back up now. You’ll be asked to sign in with Google. The backup goes into a hidden folder in your own Drive that only this game can see. On another device, open the same screen and choose Sync from Drive. Cadets combine rather than overwrite, so nothing is lost.

In a desktop web browser, open Google Drive and choose the gear icon, then Settings, then Manage apps. Find Maths & Martians, choose Options, then Delete hidden app data. This can’t be done from the Drive mobile app. You can also remove the game’s access from your Google Account’s security settings.

Open Parent Settings, choose Unlock Premium, then “Bought it before? Restore purchase”. Use the same app store account you bought with.

Free play has room for 2 cadets on a device. Premium makes room for up to 20.

In that cadet’s Parent Settings, choose Delete this cadet at the bottom, then confirm. This can’t be undone.

It keeps settings, the report and purchases in grown-up hands. It isn’t a password, and an older child may well be able to answer it, so it’s worth keeping an eye on.

No. Crystals, earned in battles, buy cosmetic extras such as hats, paint jobs and pets. Premium adds more cadets, the full report and some extra shop items. It doesn’t change the questions or how hard they are.
