🎮 Game-based learning · Grades 6–8 · India

Games can teach.
Games can assess.

Maths, entrepreneurship and financial literacy — learned by running a real business, feeling real consequences, and reading a real ledger. Never a quiz in sight — and every decision becomes evidence of what your child actually understands.

Our games

Two games, both free, both mapped to the NCERT syllabus for Classes 6–8. One runs a business at the school gate and teaches the maths behind every decision. One drops your child at an empty river valley in 3000 BCE and asks them to build a city that survives twenty years.

Lemonade Empire

"Your cart. Your business. Your maths."

Every day is a real business decision: unit costs, ratios, pricing, discounts, melting ice, rent — all the way to loans with EMI, GST and compound savings. Munshi Uncle, your accounts-man coach, narrates every evening's ledger and explains the concept behind every win and loss.

Twenty Years

"Pick a spot. Build a city. Survive the flood."

It is 3000 BCE, and the first decision is the whole lesson: where do the people settle? Plant the fields, store the grain, free hands for pots and bricks, raise the banks before the water comes — then live with twenty years of what you chose. Nobody memorises a date. They find out for themselves why the first cities in the world grew beside rivers, and then write that reason in their own words.

Why games work

Learning by consequences, not quizzes

A worksheet asks "what is 20% of 150?" A game lets you hang a 20%-off board on your own stall — and feel the margin vanish. That difference is why kids remember.

1

Make real decisions

Buy stock with limited money. Mix recipes in ratios. Set prices against rivals. Every choice is the kid's own — with their name on the shop.

2

Feel real consequences

Ice melts. Customers walk away from high prices. Discounts eat margins. The game never lectures — the market answers, and the evening ledger shows exactly why.

3

Understand the maths

Uncle narrates the day's ledger line by line, names the concept behind each result, and shows the working — then a Magic Notebook lets kids replay the day and test better decisions.

Games can assess

Anyone can claim a game teaches. Almost nobody can tell you what a child actually learned without giving them a test. We can — because in a game, every decision is evidence.

1

Decisions, not answers

A child who has never seen a percentage question has still priced 40 glasses above cost, held a 20% margin for three days, and recovered from a loss. That is demonstrated understanding — and nobody asked them a single question.

2

Gates instead of grades

The shop only grows when the evidence is there: three profitable days, priced above cost, margin held on three of the last five. A child cannot guess past a gate the way they can guess past a multiple-choice question.

3

A report built from real play

Parents and teachers see which NCERT concepts were used, where the same mistake repeated, and what changed after it. Every line traces back to a decision the child actually made.

🔍 Why this beats a score

No test anxietyNothing on screen looks like an exam
Cannot be crammedEvidence builds over days of play
Cannot be guessedA wrong price loses money, every time
Shows the recoveryHow fast a child corrects is the real signal

Growth is a function of the speed of learning — so we measure how quickly a child corrects, not only whether they arrive. See the concepts we assess →
