Number Quest is a gentle math game for kids aged 6 to 9: a cosmic voyage across the planets where your child practises addition, subtraction and times tables, earns golden stars, and unlocks new worlds. The clever part is quiet: it adapts to your child, gently serving the facts they’re still learning and celebrating real mastery. It’s 100% offline, with no ads, no tracking, and no accounts. Just open it and play.
What Number Quest is
A self-contained HTML5 math facts game that turns early arithmetic into a friendly space adventure a young child can play alone or alongside a parent.
- A planet voyage from Luna to Pluto. Seven planets (Luna, Mars, Ceres, Jupiter, Saturn, Neptune and Pluto) are gentle difficulty bands. Master a planet’s facts and the next world unlocks, so there’s real progress without pressure.
- Addition, subtraction and times tables. A simple parent setup chooses which operations to practise; multiplication (and optional sharing, ÷) appear on later planets. Operand ranges are age-appropriate at every step.
- Adaptive practice. Number Quest tracks how well your child knows each fact, on the device, and preferentially serves the weakest ones, a light, kind spaced-repetition approach, so practice goes where it’s actually needed.
- Kind multiple choice. Each puzzle offers four answers with believable “near-miss” options. A right answer earns a warm cheer; a wrong one gently shows the correct answer. No timer, no buzzer, no shaming.
- A celebratory certificate. Master a whole times-table and your child can make a gold-on-navy “Cosmic Math Certificate” to print, download or share, created right on the device.
Why parents trust it
Number Quest was built so a parent, teacher, or homeschooler never has to think twice before handing it to a child: 100% offline, no ads, no tracking, no accounts, no in-app purchases, and free.
Private & safe by design
Privacy here isn’t a setting; it’s the architecture. Number Quest makes no network calls whatsoever, so nothing ever leaves the device. Your child’s progress (unlocked planets, stars earned, and how well they know each fact) is stored locally and never uploaded. There’s no analytics, no telemetry, and no third-party code. Because it works without internet, you can use it on a tablet in airplane mode, in the car, or on a flight.
Free, with pay-what-you-want support
Number Quest is free: free on the web and free to play offline, with no ads, no accounts, and no in-app purchases. If it helps your child, you can pay what you want to support more worlds and games. It’s the second game from MEGZO_tech, made with the same privacy-first, screen-calm care as our extensions.

Number Quest: common questions
Which math operations does it cover?
Addition, subtraction and the times tables (multiplication), with optional sharing (division) on later planets. You choose which to practise in the parent setup, and can change it any time.
How does it adapt to my child?
Number Quest keeps a private, on-device record of how well your child knows each math fact and preferentially serves the ones they are still learning, a gentle weakest-first approach. It celebrates a mastered fact or table and unlocks the next planet when your child is ready.
Is it really offline?
Yes. Number Quest makes no network calls at all and runs entirely in the browser, so it works fully offline. You can also install it as an app for one-tap offline play.
Are there ads, tracking, accounts, or in-app purchases?
No, none. There are no advertisements, no analytics or tracking, no sign-up or account, and no in-app purchases. Nothing your child does is ever sent anywhere.
Is this a subscription?
No. Number Quest is free, with no recurring fees, no ads and no in-app purchases. If your family loves it, you can pay what you want to support new planets, but you never have to.

Why one-time, and why private
Most useful little tools are sold as a subscription you resent, or are free because you are the product. Neither sits right with us, so here is the trade we make instead.
-
Pay once, own it
One purchase, then it is yours. No recurring fee, no renewal you forgot about, no premium tier holding your own work hostage. The price you see is the whole price, and a license covers up to three of your devices.
-
Your data stays with you
Each tool asks for the fewest permissions it needs and does its work inside your browser. No analytics, no telemetry, no account to leak. The only call a paid extension ever makes is a license check to our own server, carrying your key and a random device id and nothing else. Your content never leaves your device.
-
Works in every Chromium browser
The extensions install and behave the same in Chrome, Brave, Edge, Opera, Vivaldi and Arc. The two games are self-contained HTML5 that also run offline and install as an app.
