Walk a friendly 3D town and finish 10 money missions
Coinville 3D: Money Missions is a free game for kids about 7 to 13, and for grown-ups who want to play along. Your child steers Cent, a gold coin with a smile, around a small low-poly town. Each mission starts with a conversation, then asks for a real decision: earn money with chores, put savings in the bank, compare prices at the market, spot a scam flyer, plan a party on a budget, give to a food drive, choose between a toy now and a bigger goal, pay back a friend, or grow tomatoes and sell them. Every mission has three stars to earn and can be played again, and 12 badges are waiting too.
Pick Explorer (ages 7 to 9) for whole-dollar numbers and shorter questions, or Pro (ages 10 to 13) for unit prices, change, interest on interest and a profit question. Play in 3D, or choose the town list: it is the same ten missions with a list of places and buttons instead of walking, so it works on any device, with a screen reader, and without a game controller or fast graphics.
What the game teaches
| Mission | Money idea |
|---|---|
| 1. Chores pay | Money is earned by work, and doing a job well matters. |
| 2. Open a savings account | A bank pays interest for keeping money there, and interest earns interest. |
| 3. Smart shopper | Unit prices, staying within a budget, wants versus needs, and counting change. |
| 4. Free at the library | Free community resources, and borrowing and returning on time. |
| 5. Spot the trick | Scam red flags: pay first, hurry, private information, too good to be true. |
| 6. Birthday party plan | A budget is a plan, and a little money kept aside covers surprises. |
| 7. Give back | Giving money, time or things, with no star ever tied to the amount. |
| 8. Toy now or a bigger goal? | Saving week by week, and what waiting costs and buys. |
| 9. Pay back a friend | Promises, trust, and the fact that borrowing can cost extra. |
| 10. Seed to sale | Profit is money in minus money out, and price changes what you sell. |
The savings interest is pretend and much bigger than real life, so children can watch money grow in a minute. Real savings accounts pay far less. After you play, try the real numbers together in the compound interest calculator and the savings goal calculator.
Tips for playing together
- Play the first two missions side by side. Let your child steer and decide, and ask what they notice.
- Ask the Talk about it question. It appears on every end screen and in the For grown-ups box, for example "Besides money, what else can we give?"
- Keep mistakes cheap. A wrong answer only shows a gentle "Oops, try again". Replay a mission for more stars.
- Print the journal. Each finished mission adds a page with the choice your child made, in numbers, and the question to talk about.
- Choose the view. Settings offer larger text, high contrast, reduced motion, simple graphics, sounds and left-handed controls. Everything works from the keyboard, with touch controls on phones, and with a gamepad.
For younger children, the coin counting game and the money jars game are shorter first steps, and Coinville Shopkeeper is a good next one. Coinville 3D is general education, not financial advice.
Frequently asked questions
Is Coinville 3D free, and does my child need to download anything?
It is free, with no sign-up, no ads and no third-party trackers, and nothing to install. The 3D engine loads only when your child presses Play in 3D. Nobody types a name or anything personal. Stars, badges and settings are saved only in your browser on this device, and the For grown-ups box has a button that deletes them. We keep only anonymous counts, such as how many missions are finished, with no cookies and nothing that identifies a child.
What if my device cannot show 3D, or my child prefers reading?
Choose "Play with the town list (no 3D)". It starts automatically if your browser has no WebGL, and the game switches to it if the 3D picture ever stops working. The list shows every place with a short description and where it is, and each place has buttons for the things you can do there. Every mission and every star can be earned this way, and the dialogue is always real text on the page.
Is the interest in the savings mission real, and is this financial advice?
No. The game pays 10 percent a month so that children can see money grow quickly. Real rates are quoted per year and are much lower. The prices, wages and fees in the missions are pretend too. Coinville 3D is a way to start money conversations at home, not financial, tax or legal advice.
