Learn why investing looks easier after the fact
Blindfolio teaches through surprise: you make the decisions first, then discover the famous era and real companies behind them.
Concepts inside the game
Players naturally meet diversification, compounding, drawdowns, concentration risk, inflation, interest rates, and the problem of seeing only the survivors.
Short feedback loop
A round takes minutes, but the result covers years. That makes abstract investing lessons concrete very quickly.
No investment advice
Blindfolio is an educational game. It uses history to teach uncertainty, not to recommend real trades.
