Roblox, Fortnite, Minecraft, Xbox, Nintendo, PlayStation, Steam — whatever they actually want. You buy the gift code once and seal it in their vault. They can see the prize the whole time, but it only opens once they've earned it, one question at a time.
Free to practise. The vault is $4.99 a month. Your kid never signs in to anything.
Any code you can buy, they can earn. You choose which ones go in the vault.
You hold the gift card balance, not us. Your child never has an account or a password — you set their device up once with a code, and after that it just opens.
You hold the gift card balance, not us. Buy a digital code — $10 of Roblox Credit, a $10 Xbox card, $20 on Steam — and paste it into the parent tab. Or buy it inside the app and skip the pasting. You decide what it costs them in coins.
Daily goal, adaptive drilling that chases the facts they keep missing, a streak they don't want to break. Right answers pay coins. Fast answers pay more.
They hit the number, tap Open, and the code is theirs — with a button straight to the redeem page. Until that moment they can see the prize but never the code.
The prize sits in front of them the whole time. They can see exactly what it costs and exactly how close they are — and the code stays sealed until the number lands.
They pick their level at the start of every session. Beginner is multiple choice for kids still counting on fingers; Master is a seven-second clock with everything mixed together.
Pick from four answers, no clock
×1Type it in, take your time
×2Beat the timer bar
×3Fast clock, all skills mixed
×4Pick a skill and narrow it to the slice they're actually working on this week — just the 4s, 5s and 6s, or only halves and quarters.
Gift codes are sold at face value. We add the card processing fee and nothing else — Learn4Coins keeps zero on every code. The subscription is what pays for the app.
| Card | You pay | Processing | We keep |
| $10 Roblox Credit | $10.61 | $0.61 | $0.00 |
| $25 Xbox | $26.06 | $1.06 | $0.00 |
Card networks charge a percentage plus a flat fee per transaction, and most of it goes to the bank that issued the card — not to us and not to the processor. It hits small purchases hardest: about 9% on a $4.99 card, 4% on a $25 one. Buying one larger card instead of several small ones costs less.
Prefer not to buy codes here at all? Buy a gift card wherever you already shop and paste the code into the vault — we take nothing on top of it, and never will. The subscription is for the vault itself, not for the card.
No, and neither can anything else. Roblox has no account-to-account transfer — even you can't send Robux to your own child from your own account. Every legitimate route ends in a redemption code. Anything promising otherwise wants their password.
Wherever you like — Roblox.com, Amazon, Target, the Microsoft store. Paste it into the parent tab and it's sealed. You can also buy one inside the app, which drops it into the vault automatically.
Wrong answers get re-asked later in the same session, so guessing costs them time rather than earning coins. The daily cap limits any grinding, and codes are hidden until they're unlocked. They could dig them out with browser developer tools — if you have that kind of kid, leave auto-unlock off and approve payouts yourself.
Three separate things. Practising is free — every subject, every level, coins, streaks and badges, for as long as you like. The vault is $4.99 a month: sealing a real gift card away so it has to be earned. Cancel and anything already sealed can still be opened. Rewards are whatever you choose: you set how many coins a fact is worth and how many coins a dollar costs, and the parent screen shows the worst case in dollars per week before you hand over the iPad. Codes are sold at face value — we keep nothing.
Nothing, if you made an account — sign in on the new device and the streak, the coins and the sealed codes come straight back. Without one it's gone, so there's also an Export button in the parent tab that writes a backup file.
Name, avatar, level, daily goal, a PIN they don't know. Then load one code and let them find it.
