Tangyuan Math❓ Frequently asked questions
Is it free?
Yes. All practice modes — untimed Practice, the 10-level Challenge and mistake review — are free.
Do I need an account?
No. The game works fully without registration. (Optional parent accounts for cloud backup may come later — the free game will keep working without them.)
Where is my data stored?
In your own browser (local storage). Practice records, your mistake book and settings never leave your device. You can clear everything anytime in the game's Settings.
Are there ads or trackers?
No ads, no analytics, no third-party scripts or fonts. The page loads everything from this site only.
Who is it for?
Learners who already know their times tables and want to get comfortable with bigger multiplication — at home, homeschool, or as classroom practice.
Which languages are supported?
English and Chinese (中文). Switch anytime from the top of the game screen.
Does it work on phones and tablets?
Yes — it's designed for touch, keyboard and screen readers alike. Enter jumps to the next question on physical keyboards.
Will there be paid features?
Maybe later — ideas include printable PDF worksheets, kept optional for families. The free practice game will stay complete on its own, and we'll never add ads.
