Number Ninjas — Support

Number Ninjas is a fast, friendly mental-maths game for young learners (roughly ages 8–12). Pick a difficulty and which operations to practise, then race the clock answering quick-fire questions to build streaks, earn stars, and beat your best score. Everything runs on your device.

FAQ

How do I play?

Choose a difficulty (Easy, Medium, or Hard) and tap the operations you want to practise — addition, subtraction, multiplication, division — then press Start. Tap the correct answer for each question. A correct answer keeps your streak alive; three lives, ten questions per round.

How is my score calculated?

Each correct answer is worth points, with a bonus once you reach a streak of three or more in a row. At the end you get one to three stars based on how many you answered correctly, and your best score is saved.

Which difficulty should my child start with?

Easy uses single-digit numbers, Medium focuses on times-tables-range values, and Hard mixes larger numbers and all operations. Start on Easy and move up as confidence grows.

Did I lose my best score?

Your best score is saved on your device only. Deleting the app removes it, and because there is no account or cloud sync, it does not transfer to a new device.

Does it need the internet or any permissions?

No. Number Ninjas works completely offline and asks for no permissions — no location, contacts, camera, or notifications. There are no accounts and no sign-ups.

Is there anything to buy?

No. Number Ninjas is free, with no in-app purchases and no advertising.
