Run an economics game with your class
Here's how to run a live economics experiment with your class in a single lesson: pick a game, students join with a code on any phone (no accounts), you steer the rounds from a live dashboard, and then you debrief together.
One lesson, one game, the whole class playing at once — no student sign-ups and no installs, just phones and a code on the board.
Pick a game
Open /play and browse the multiplayer games. Each card shows the learning goals, timing, recommended class size and difficulty — and a lesson plan is built in. Good first choices are Double Auction, Market Day, Public Goods and Ultimatum.
Start with one of these:Share the session code
Create a session and a short code appears — write it on the board. Students open /join, type the code and their name, and they're in: no account, email or password, on any phone or laptop. Odd number in the room? Bots fill the empty seats so the pairing always works.

Run the rounds
You drive the lesson from the live teacher dashboard: advance each round when the class is ready and watch the results arrive as students act. For a 45-minute lesson a rough split is 10 minutes to set up and explain, 25 to play the rounds, and 10 to debrief.
Debrief together
Every game ships with discussion questions and a results screen that compares the class's outcomes. Use them to connect what just happened on the phones back to the concept — the aha-moment lands when students see their own numbers.
Print certificates
After the session you can download batch certificates for the whole class — fun or serious — each carrying the student's name. Anyone can confirm one at /verify.
Go beyond one lesson
Assign a practical task — an individual simulation experiment plus a written report, with a teacher dashboard that flags likely AI-written work — set a graded Series A test from /tests, or tie the lesson to a book chapter from /books.
Teacher FAQ
- Do students need accounts?
- No. Students join with the session code and a name at /join — no account, email or password. Their participation stays pseudonymous, so there's no student personal data to manage.
- How many players can join?
- Up to 40 students can join a session from their phones. Bots fill any empty or odd seats, so games that need pairs or groups still work.
- What if the class has an odd number?
- Bots automatically fill the odd seat, so every student gets a partner or group and no one has to sit a round out.
- What devices do students need?
- Any phone, tablet or laptop with a browser. There's nothing to download or install, and one device per student is enough to join.
- Is it free?
- Yes. Running games with your class is free, and the teacher account — the only account involved — is free too.
- Can I reuse a game with another class?
- Yes. Create a fresh session whenever you like; each one gets its own code, so you can run the same game with as many classes as you want.
No classroom? You can host the same multiplayer games at home — you against your family, in about fifteen minutes, with no account needed. Play at home
