Common questions

Does it cost anything? No. Sum Rush is free, with no ads and no in-app purchases. Coins are earned by answering questions, and that is the only way to get them.

Does it need the internet? No. Races, Solo Sprint, the Daily Challenge, Practice, the shop and the maths coach all work offline. Only the live leagues need a connection; offline, the League screen shows a practice room of computer players instead.

Are the other racers real people? The three rivals in a race are computer racers that match your recent speed, so races stay close. The league rooms and the World and Top Races boards are real players.

How do I change my name? On the Me screen, tap the dice for a new made-up name. Names are invented by the game, and nobody can type one in, so no real names ever appear on the boards.

How do I turn the online leagues off? Settings → Online leagues. With it off, the game sends nothing.

How do levels unlock? Win a race at your top level (or score 25 or more in a Solo Sprint) to open the next level of that topic. Every times table from 2 to 12 is open from the start.

What are the tricky ones? The coach notices the questions you find hard (like 7 × 8, or carrying in addition) and lists them on the home screen. Practise them gives you 20 questions with no clock, and How to remember it shows a tip for that kind of sum. My maths on the Me screen shows how you are going in each topic.

My progress disappeared. Progress is stored on the device only, so deleting and reinstalling the app clears it. There is no cloud save and no account to restore from.

There is no sound. Check the phone's silent switch and volume, then Settings → Sound in the game.

Can I have my league record deleted? Yes. Email support@bendigogames.com with the made-up name from the Me screen.

Privacy

The game keeps your progress on the device. The live leagues share only a made-up name, scores and an anonymous player number. No ads, no analytics, no tracking. The full details are in the privacy policy.
