Teach investing
they actually get.
Doubloon is a free game where students practice investing with paper money and real market data — no real cash and no gambling, ever. Spin up a class in seconds and watch them learn by doing.
Why teachers use it
Safe, standards-aligned, and genuinely fun — so the learning sticks.
Safe by design
Paper money only — students can't lose or spend real cash. No gambling mechanics; it rewards patience and diversification, not reckless trading.
Standards-aligned
Maps to the Investing and Financial Decision-Making standards (Jump$tart / CEE) most personal-finance courses are built on.
Class mode built in
Create a class, students join with one 6-character code, and everyone competes on a single live class leaderboard.
Lessons + real practice
Bite-size lessons teach one concept at a time — diversification, index funds, risk — then students apply it with live market data.
Run it in your class in 3 steps
No setup headaches — one code and you're teaching.
Create your class
Name it and pick a term — quarter, semester, or full year. Takes about 30 seconds.
Students join with a code
Share one 6-character code. No accounts to manage, nothing for them to download.
They learn by doing
Lessons teach the concepts; a live class leaderboard blends what they learn with how they invest.
Built for the classroom
Everything about it is designed to be safe for minors.
Paper money only
No real trading, no purchases, no way to lose real money. It's practice.
Minimal data, no ads
We collect as little as possible and never run ads targeting students.
Accessible
Keyboard-navigable, WCAG AA contrast, and screen-reader labels throughout.
Bring it to your classroom.
Free forever for students and teachers. Make a class and share the code.
