Start with pieces
Tap each colored chunk twice. Then choose the missing piece and practice filling in the ending first. Leading zeros stay put.
Remember Your Numbers · Free & open source
A little practice. A number that sticks.
A gentle practice game for the numbers you want to remember. Tap their colored pieces, spot what’s missing, and work toward typing the whole thing from memory.
Fictional demo included · No account · Simple local setup
Build to recall
Try the whole number with a first-digit hint, then without it. Come back at least 20 hours later to prove you remember.
Keep it fresh
A clean proof starts a two-day review interval. Successful reviews spread farther apart, up to 30 days. A miss brings practice closer again.
The actual game
Just the next little step.
Try the fictional Nova or Orion examples first. For your own setup, press Add my own numbers, enter a nickname and a number, and choose its chunk sizes.
A ten-digit number can use 3, 3, 4: three digits, three digits, then four. Use the big keypad, or your computer’s number keys. Each learner can practice several numbers.
Sound starts off. When you turn it on, the game uses only voices your browser reports as local. If none is available, practice silently and say the pieces yourself.
Keep it, use it, share it
No computer skills required.
Press Try the game for the easiest start. On a computer, you can also keep the complete game in a single file that works without the internet.
- Download the game. Save Remember-Your-Numbers.html somewhere you can find it.
- Double-click the file. It opens in your browser. If it opens as text, right-click, choose Open with, and select your browser.
- Try a demo learner or add your own numbers. No GitHub account, terminal, installation or AI subscription is needed.
On a phone? The Try the game link is usually easier. Different browsers and downloaded copies can keep separate saves; a backup lets you move them.
Your numbers, your browser
Keep a private backup.
The game has no account, cloud save or analytics. It saves your setup and progress in this browser when safe local storage is available. Use a private device: someone using the same browser can open the same numbers.
In Setup and backups, press Export backup. That file contains your numbers and progress in readable text, so keep it private. Clearing browser data can erase local saves. If saving is unavailable, the game says so and still lets you export.
If another tab changes or erases the setup, the older tab stops saving and asks you to reload or export its older copy.
Built for me. Yours to adapt.
Make it your own.
I built this for my own personal use, around the way I wanted to practice important numbers. Make it your own, and feel free to improve mine. Hopefully it gives you a useful starting point, or at the very least some ideas. Cheers!
The complete game, learning logic, design notes, tests and an AI-assistant adaptation skill are on GitHub. This page uses a fixed release of that same public engine.
