Four worlds, one adventure
Add in a glowing forest, subtract through desert canyons, multiply up snowy peaks, and divide beneath the ocean. Each world has 15 levels and a boss gate.
A cosmic math adventure
Big adventures.
Little mathematicians.
Four magical worlds, four quick arcade games, and daily quests that turn addition, subtraction, multiplication, and division into play. No ads. No accounts. Works offline.

Why it clicks
Play first. Practice quietly.
Short sessions, visible progress, and just enough challenge. Math Monsters keeps the next step obvious so kids can get on with the fun.
Arcade breaks that teach
Math Runner, Memory Match, Bubble Pop, and Power Streak each remix arithmetic into a different kind of quick, replayable challenge.
Daily quests, earned stars
Small goals bring kids back without pressure. Stars are earned by playing and spent on cosmetics—never bought with real money in this release.
Progress that saves
Stars, XP, level unlocks, and cosmetics persist on the device. Close the app mid-run and the adventure is still there next time.
A parent view that makes sense
Accuracy, time played, mistake patterns, and a weekly report—behind a grown-up gate, written in plain language rather than dashboard jargon.
Comfort by design
200% text support, reduced motion, high contrast, a color-blind palette, and adjustable haptics. The game adapts instead of asking kids to cope.
The adventure map
Four worlds.
One growing hero.
Each world focuses on one operation, then mixes it with what came before. Levels are finite, so “finished” means finished—and replaying never moves progress backwards.
Addition
Addition Forest
Friendly forest creatures and a guardian who cheers every correct answer.
15 levels
Subtraction
Subtraction Desert
Count down through canyon trails and learn to take away with confidence.
15 levels
Multiplication
Multiplication Mountains
Climb in groups and patterns, turning repeated addition into a superpower.
15 levels
Division
Division Ocean
Share fairly beneath the waves and discover the inverse of multiplication.
15 levelsMath Arcade
Four ways to get hooked.
When a full level feels like a lot, the arcade offers a two-minute win. Each game has its own pacing, its own HUD, and the same arithmetic underneath.
Math Runner
Answer to keep running, jump obstacles, and chase a longer streak.
Memory Match
Pair equations with answers and remember where each card hides.
Bubble Pop
Pop the right answer before it floats away. Combos reward accuracy.
Power Streak
Keep the streak alive and build a multiplier that feels enormous.
A look inside
Designed for small hands,
not tiny screenshots.
Every screen below is from the current build. The browser demo is the same game—scroll the strip, or jump in and play a level.
For grown-ups
Kids get an adventure.
You get the receipts.
The parent dashboard shows what was practised, what was missed, and how time adds up—without turning play into a performance review.
- A grown-up gate keeps reports and controls out of small hands.
- Device-only progress. No account, cloud sync, ads, or third-party analytics.
- Weekly reports and mistake practice in plain language, with local PDF export.
- Data you can delete. Reset or export the on-device profile from the parent area.
The parent report above is an illustrative view. The browser demo stores progress in this browser only and runs the same release-candidate build as the mobile app.
Questions
Good to know.
Is Math Monsters free?
Pricing will be confirmed at launch. The browser demo is free to play, and the release version uses stars earned through play—not real-money purchases.
Does it need an internet connection?
The mobile app is built to work offline: worlds, voice lines, music, and progress are all local. The browser demo needs the page loaded first.
What ages is it for?
It is designed for children practising early arithmetic—addition through division—with a grown-up nearby for the parent areas. Text size, motion, contrast, and haptics can be adjusted.
Is my child's data uploaded?
No. There are no accounts, ads, or third-party analytics. Progress and learning history stay on the device, behind an encrypted local store. Grown-ups can export or reset the profile.
Which languages are included?
English, Japanese, and Simplified Chinese—including interface copy, gameplay voice lines, and parent report output.
Is multiplayer included?
Not in the 1.0 offline release. The app focuses on a single-player adventure; a local friend-match prototype is not shipped in release builds.
Where can I play it?
The browser demo is available now at math-monsters.vietprohub.com/play. iOS and Android releases are being prepared for the App Store and Google Play.
What accessibility options exist?
200% system text, reduced motion, high contrast, a color-blind answer palette, screen-reader labels, and adjustable haptics. Physical-device screen-reader testing is still in progress.
