Learning games for investors and traders
Short, honest simulations that let you feel the maths of risk, the pull of emotions and the power of compounding, before any of it costs real money. No sign-up, no real money, no prizes.
Risk and position sizing
The maths that decides whether a trader survives long enough for an edge to matter.
The Biased Coin Challenge
A coin lands heads 60% of the time and pays even money. Grow ₹10,000 in 100 flips.
You learn: Why bet size decides outcomes even with an edge; the Kelly criterion.
About 5 minutesThe Blown-Account Challenge
A profitable strategy, 100 trades, and one decision: how much to risk on each.
You learn: How losing streaks and position size decide whether an account survives.
About 5 minutesWin Rate vs Reward-to-Risk Explorer
Set win rate, payoff and costs; simulate 30 traders; then take the profitable-or-not quiz.
You learn: Expectancy, break-even win rates and the role of luck.
About 6 minutesRisk of Ruin Simulator
1,000 simulated traders with the same rules and different luck.
You learn: How risk per trade turns into the probability of ruin.
About 4 minutesThe Drawdown Recovery Game
Guess the gain needed to recover from losses, then see real NIFTY 50 falls.
You learn: The asymmetry of losses and how long recoveries take.
About 4 minutesInvestor behaviour
The emotional traps (averaging into losers, chasing hype, reacting to headlines) that cost investors the most.
Catching a Falling Knife
A stock you own has fallen 20%. Buy more, hold or sell as monthly news arrives.
You learn: Telling a temporary setback from a value trap; the arithmetic of averaging down.
About 6 minutesThe Market Timing Showdown
Real NIFTY 50 months with dates hidden: invested or cash, month by month.
You learn: Why timing the market is hard; trend rules versus reacting to headlines.
About 7 minutesThe FOMO Chase
Three hot stocks, a social feed and a hype meter, in real time.
You learn: How hype pushes investors to buy late, and defences that work.
About 6 minutesInvesting maths
Averaging and compounding, the two quiet engines of long-term wealth.
The Rupee-Cost Averaging Lab
SIP vs lumpsum vs waiting for a dip, in five kinds of market.
You learn: Why a SIP's average cost is below the average price, and when lumpsum wins.
About 4 minutesThe Compounding Race
An early starter, a late starter and a steady investor race to age 60.
You learn: Time as the engine of compounding; the Rule of 72.
About 3 minutesWhy learn with games?
Most investing mistakes are not caused by a lack of information. People know that markets fall, that losing streaks happen and that tips are unreliable, yet they still bet too much, chase rallies and sell in panics. Knowing a fact and feeling it are different things.
A short simulation closes that gap. Watching a profitable strategy blow up an account because the bets were too large, or seeing your own late purchase marked at the top of a hype cycle, makes the lesson stick in a way that a paragraph cannot. Every game is followed by an explanation of the maths and links to the articles that go deeper.
Ground rules
- No real money and no prizes. All amounts are virtual. Nothing here is a trading platform or a contest.
- Honest randomness. Games use your browser's random number generator, and most show at the end exactly how the outcome was generated. Where we use real market data (the NIFTY 50 in the timing showdown, the drawdown game and the SIP lab), we say so.
- Nothing is stored or sent. The games run entirely in your browser.
- Simulations simplify. Real markets have costs, taxes, gaps and changing conditions. The lessons are about principles, not predictions. Read our disclaimer.
