One period. No installs.
No student logins.

Your students run a business and are scored on the profit they make. It uses unit cost, ratio, percentages and break-even — applied, not recited. You get a report showing which concepts your class is strong and weak on.

What it takes from you

1
Nothing to install. Any browser, any laptop or tablet. If your lab runs YouTube, it runs this.
2
No student accounts. Students type a class code, their first name and roll number. That is the entire sign-in, and the entire data collection.
3
One period. About 30 minutes of play. Everyone finishes inside a single period.
4
A report afterwards. Which concepts your class handled and which they did not — by name, at class level.

What your students are assessed on

Unit cost

Class 6 — Unitary Method. Buying by the dozen, working out what one costs.

Ratio & proportion

Class 6 — scaling a recipe when the batch size changes.

Percentages & margin

Class 7 — Comparing Quantities, used to hold a profit margin.

Discounts

Class 8 — Comparing Quantities, and what a discount really costs.

Break-even

Class 8 — Linear Equations, with a reason to exist.

Data handling

Class 6–8 — reading their own sales back and deciding what to change.

Why it works in a classroom

✅ Everyone plays the same market. On a given day every student faces identical weather, prices and events — so the class debrief is a real argument about what the right price was.
✅ No child is publicly ranked bottom. The class competes as a team against other classes, so a weak student's ₹40 still counts for their side.
✅ It survives your wifi. The game keeps running offline and submits scores when the connection returns.
✅ You can use it as a lesson starter or a full activity. Three days of trading is 30 minutes; one day is under 10.
Free for teachers and schools, permanently. Not a trial, not a freemium tier that expires. We charge parents for a home subscription; classrooms are how the work gets to children who would never find it otherwise, and we are not going to put a price on that.

Questions teachers ask

What data do you collect from my students?A first name and a roll number. No phone number, no email, no photograph, no address. Students are never asked to create an account or a password.
Will you contact my students' parents?Not from anything the school gives us — we never ask a school for parent contact details. Students carry home a certificate; if a parent chooses to scan it, they start their own account with their own consent.
Can I see what my class did?Yes. After a session you get a class report: participation, average profit, and which concepts came out strong and weak.
What is the Olympiad?A free inter-school competition on 15, 20 or 23 October 2026. Same format, one period, plus certificates for every participating student and a school report. Details here.
Do I need to prepare anything?No. We send class codes and a one-page instruction sheet three days before. You read out six lines and supervise.
